Mojibake ( 文字化け ; IPA: [mod͡ʑibake]) is the garbled text that is the result of text being decoded using an unintended character encoding.[1] The consequence is a systematic replacement of symbols with completely unrelated ones, often from a unlike writing system.
This display may include the generic replacement graphic symbol ("�") in places where the binary representation is considered invalid. A replacement tin can also involve multiple sequent symbols, as viewed in one encoding, when the same binary code constitutes one symbol in the other encoding. This is either because of differing constant length encoding (as in Asian 16-chip encodings vs European 8-bit encodings), or the use of variable length encodings (notably UTF-viii and UTF-16).
Failed rendering of glyphs due to either missing fonts or missing glyphs in a font is a different outcome that is non to be dislocated with mojibake. Symptoms of this failed rendering include blocks with the code point displayed in hexadecimal or using the generic replacement graphic symbol. Importantly, these replacements are valid and are the result of right error handling by the software.
Etymology [edit]
Mojibake means "character transformation" in Japanese. The word is composed of 文字 (moji, IPA: [mod͡ʑi]), "character" and 化け (broil, IPA: [bäke̞], pronounced "bah-keh"), "transform".
Causes [edit]
To correctly reproduce the original text that was encoded, the correspondence between the encoded data and the notion of its encoding must be preserved. As mojibake is the instance of not-compliance between these, information technology can be achieved by manipulating the information itself, or merely relabeling it.
Mojibake is often seen with text data that have been tagged with a wrong encoding; it may non fifty-fifty exist tagged at all, merely moved between computers with different default encodings. A major source of trouble are communication protocols that rely on settings on each computer rather than sending or storing metadata together with the data.
The differing default settings between computers are in part due to differing deployments of Unicode among operating system families, and partly the legacy encodings' specializations for dissimilar writing systems of man languages. Whereas Linux distributions mostly switched to UTF-8 in 2004,[2] Microsoft Windows by and large uses UTF-xvi, and sometimes uses 8-fleck code pages for text files in unlike languages.[ dubious ]
For some writing systems, an example being Japanese, several encodings take historically been employed, causing users to see mojibake relatively often. Equally a Japanese case, the word mojibake "文字化け" stored as EUC-JP might exist incorrectly displayed equally "ﾊｸｻ�ｽ､ｱ", "ﾊｸｻ嵂ｽ､ｱ" (MS-932), or "ﾊｸｻ郾ｽ､ｱ" (Shift JIS-2004). The same text stored as UTF-eight is displayed as "譁�蟄怜喧縺�" if interpreted every bit Shift JIS. This is further exacerbated if other locales are involved: the aforementioned UTF-eight text appears equally "æ–‡å—化ã'" in software that assumes text to be in the Windows-1252 or ISO-8859-1 encodings, usually labelled Western, or (for example) equally "鏂囧瓧鍖栥亼" if interpreted as being in a GBK (Mainland China) locale.
| Original text | 文 | 字 | 化 | け | ||||
|---|---|---|---|---|---|---|---|---|
| Raw bytes of EUC-JP encoding | CA | B8 | BB | FA | B2 | BD | A4 | B1 |
| Bytes interpreted every bit Shift-JIS encoding | ﾊ | ｸ | ｻ | 郾 | ｽ | ､ | ｱ | |
| Bytes interpreted as ISO-8859-1 encoding | Ê | ¸ | » | ú | ² | ½ | ¤ | ± |
| Bytes interpreted as GBK encoding | 矢 | 机 | 步 | け | ||||
Underspecification [edit]
If the encoding is non specified, it is up to the software to determine information technology by other ways. Depending on the type of software, the typical solution is either configuration or charset detection heuristics. Both are prone to mis-prediction in not-so-uncommon scenarios.
The encoding of text files is affected by locale setting, which depends on the user's language, make of operating arrangement and mayhap other conditions. Therefore, the assumed encoding is systematically wrong for files that come from a figurer with a different setting, or even from a differently localized software within the same arrangement. For Unicode, i solution is to use a byte order mark, but for source code and other machine readable text, many parsers don't tolerate this. Some other is storing the encoding equally metadata in the file arrangement. File systems that support extended file attributes can shop this as user.charset.[iii] This also requires support in software that wants to take advantage of it, simply does not disturb other software.
While a few encodings are piece of cake to observe, in particular UTF-viii, at that place are many that are hard to distinguish (meet charset detection). A spider web browser may not be able to distinguish a page coded in EUC-JP and another in Shift-JIS if the coding scheme is non assigned explicitly using HTTP headers sent along with the documents, or using the HTML certificate's meta tags that are used to substitute for missing HTTP headers if the server cannot exist configured to ship the proper HTTP headers; see character encodings in HTML.
Mis-specification [edit]
Mojibake also occurs when the encoding is wrongly specified. This often happens between encodings that are like. For example, the Eudora email client for Windows was known to ship emails labelled as ISO-8859-1 that were in reality Windows-1252.[4] The Mac Bone version of Eudora did non showroom this behaviour. Windows-1252 contains actress printable characters in the C1 range (the most frequently seen being curved quotation marks and extra dashes), that were not displayed properly in software complying with the ISO standard; this peculiarly affected software running under other operating systems such every bit Unix.
Human being ignorance [edit]
Of the encodings however in use, many are partially compatible with each other, with ASCII as the predominant common subset. This sets the stage for homo ignorance:
- Compatibility can be a deceptive property, equally the common subset of characters is unaffected by a mixup of 2 encodings (meet Problems in different writing systems).
- People think they are using ASCII, and tend to label whatever superset of ASCII they really use every bit "ASCII". Possibly for simplification, just fifty-fifty in academic literature, the word "ASCII" tin can be found used as an example of something not compatible with Unicode, where obviously "ASCII" is Windows-1252 and "Unicode" is UTF-8.[1] Annotation that UTF-8 is backwards uniform with ASCII.
Overspecification [edit]
When there are layers of protocols, each trying to specify the encoding based on different information, the least certain information may exist misleading to the recipient. For example, consider a web server serving a static HTML file over HTTP. The character set may be communicated to the client in whatsoever number of 3 means:
- in the HTTP header. This data can be based on server configuration (for instance, when serving a file off disk) or controlled past the application running on the server (for dynamic websites).
- in the file, equally an HTML meta tag (
http-equivorcharset) or theencodingattribute of an XML announcement. This is the encoding that the author meant to salvage the particular file in. - in the file, every bit a byte society mark. This is the encoding that the author's editor actually saved it in. Unless an accidental encoding conversion has happened (by opening it in ane encoding and saving it in some other), this volition be right. Information technology is, however, but available in Unicode encodings such as UTF-8 or UTF-xvi.
Lack of hardware or software support [edit]
Much older hardware is typically designed to back up only one character set and the graphic symbol fix typically cannot be altered. The character tabular array contained within the display firmware will be localized to have characters for the country the device is to exist sold in, and typically the table differs from country to state. As such, these systems will potentially display mojibake when loading text generated on a system from a different country. Likewise, many early operating systems do not back up multiple encoding formats and thus will end up displaying mojibake if made to display non-standard text—early versions of Microsoft Windows and Palm Bone for example, are localized on a per-country basis and will only support encoding standards relevant to the country the localized version will be sold in, and volition brandish mojibake if a file containing a text in a unlike encoding format from the version that the OS is designed to support is opened.
Resolutions [edit]
Applications using UTF-eight equally a default encoding may achieve a greater degree of interoperability considering of its widespread use and astern compatibility with US-ASCII. UTF-8 too has the ability to be direct recognised by a simple algorithm, and then that well written software should be able to avoid mixing UTF-8 up with other encodings.
The difficulty of resolving an instance of mojibake varies depending on the awarding inside which it occurs and the causes of it. Two of the nigh common applications in which mojibake may occur are web browsers and word processors. Modern browsers and word processors often back up a wide array of graphic symbol encodings. Browsers often allow a user to change their rendering engine's encoding setting on the wing, while word processors allow the user to select the appropriate encoding when opening a file. It may take some trial and mistake for users to find the correct encoding.
The problem gets more complicated when it occurs in an application that commonly does not support a wide range of character encoding, such as in a non-Unicode computer game. In this instance, the user must change the operating organization'southward encoding settings to lucifer that of the game. Even so, irresolute the system-wide encoding settings can too cause Mojibake in pre-existing applications. In Windows XP or afterward, a user too has the option to employ Microsoft AppLocale, an application that allows the changing of per-application locale settings. Even so, changing the operating system encoding settings is not possible on earlier operating systems such equally Windows 98; to resolve this outcome on earlier operating systems, a user would accept to use 3rd party font rendering applications.
Problems in different writing systems [edit]
English [edit]
Mojibake in English texts generally occurs in punctuation, such as em dashes (—), en dashes (–), and curly quotes (",",','), merely rarely in character text, since most encodings agree with ASCII on the encoding of the English alphabet. For example, the pound sign "£" will appear as "£" if it was encoded by the sender as UTF-8 merely interpreted by the recipient as CP1252 or ISO 8859-ane. If iterated using CP1252, this can lead to "£", "£", "ÃÆ'‚£", etc.
Some computers did, in older eras, have vendor-specific encodings which caused mismatch also for English language text. Commodore make eight-bit computers used PETSCII encoding, particularly notable for inverting the upper and lower instance compared to standard ASCII. PETSCII printers worked fine on other computers of the era, merely flipped the case of all messages. IBM mainframes utilize the EBCDIC encoding which does not match ASCII at all.
Other Western European languages [edit]
The alphabets of the North Germanic languages, Catalan, Finnish, German, French, Portuguese and Castilian are all extensions of the Latin alphabet. The additional characters are typically the ones that become corrupted, making texts only mildly unreadable with mojibake:
- å, ä, ö in Finnish and Swedish
- à, ç, è, é, ï, í, ò, ó, ú, ü in Catalan
- æ, ø, å in Norwegian and Danish
- á, é, ó, ij, è, ë, ï in Dutch
- ä, ö, ü, and ß in German language
- á, ð, í, ó, ú, ý, æ, ø in Faroese
- á, ð, é, í, ó, ú, ý, þ, æ, ö in Icelandic
- à, â, ç, è, é, ë, ê, ï, î, ô, ù, û, ü, ÿ, æ, œ in French
- à, è, é, ì, ò, ù in Italian
- á, é, í, ñ, ó, ú, ü, ¡, ¿ in Spanish
- à, á, â, ã, ç, é, ê, í, ó, ô, õ, ú in Portuguese (ü no longer used)
- á, é, í, ó, ú in Irish gaelic
- à, è, ì, ò, ù in Scottish Gaelic
- £ in British English
… and their uppercase counterparts, if applicable.
These are languages for which the ISO-8859-1 character prepare (also known equally Latin i or Western) has been in use. Withal, ISO-8859-ane has been obsoleted past two competing standards, the astern compatible Windows-1252, and the slightly altered ISO-8859-15. Both add the Euro sign € and the French œ, but otherwise any confusion of these three character sets does non create mojibake in these languages. Furthermore, it is always prophylactic to translate ISO-8859-1 every bit Windows-1252, and fairly safe to interpret it as ISO-8859-15, in item with respect to the Euro sign, which replaces the rarely used currency sign (¤). However, with the advent of UTF-8, mojibake has become more common in certain scenarios, eastward.thou. exchange of text files between UNIX and Windows computers, due to UTF-8's incompatibility with Latin-1 and Windows-1252. Simply UTF-8 has the ability to be directly recognised by a simple algorithm, and so that well written software should exist able to avert mixing UTF-8 up with other encodings, so this was most mutual when many had software non supporting UTF-eight. Well-nigh of these languages were supported past MS-DOS default CP437 and other machine default encodings, except ASCII, so problems when buying an operating system version were less common. Windows and MS-DOS are non compatible notwithstanding.
In Swedish, Norwegian, Danish and High german, vowels are rarely repeated, and it is usually obvious when ane character gets corrupted, e.g. the 2nd letter of the alphabet in "kärlek" ( kärlek , "love"). This way, even though the reader has to guess betwixt å, ä and ö, almost all texts remain legible. Finnish text, on the other hand, does feature repeating vowels in words like hääyö ("hymeneals night") which can sometimes render text very hard to read (e.grand. hääyö appears as "hääyö"). Icelandic and Faroese accept ten and 8 possibly confounding characters, respectively, which thus tin can go far more than difficult to judge corrupted characters; Icelandic words like þjóðlöð ("outstanding hospitality") become about entirely unintelligible when rendered as "þjóðlöð".
In German, Buchstabensalat ("letter salad") is a common term for this phenomenon, and in Spanish, deformación (literally deformation).
Some users transliterate their writing when using a reckoner, either by omitting the problematic diacritics, or by using digraph replacements (å → aa, ä/æ → ae, ö/ø → oe, ü → ue etc.). Thus, an author might write "ueber" instead of "über", which is standard do in German when umlauts are not available. The latter practice seems to be better tolerated in the High german language sphere than in the Nordic countries. For instance, in Norwegian, digraphs are associated with archaic Danish, and may be used jokingly. However, digraphs are useful in communication with other parts of the world. As an example, the Norwegian football player Ole Gunnar Solskjær had his proper name spelled "SOLSKJAER" on his back when he played for Manchester United.
An antiquity of UTF-eight misinterpreted every bit ISO-8859-1, "Ring meg nÃ¥" (" Band 1000000 nå "), was seen in an SMS scam raging in Norway in June 2014.[5]

| UTF-8 | ISO 8859-1 | Smörgås |
| UTF-viii | Mac Roman | Smörgås |
Cardinal and Eastern European [edit]
Users of Central and Eastern European languages can also be affected. Because most computers were not connected to any network during the mid- to belatedly-1980s, there were dissimilar character encodings for every language with diacritical characters (see ISO/IEC 8859 and KOI-8), oft also varying by operating system.
Hungarian [edit]
Hungarian is another affected linguistic communication, which uses the 26 basic English language characters, plus the accented forms á, é, í, ó, ú, ö, ü (all nowadays in the Latin-one character set), plus the two characters ő and ű, which are not in Latin-one. These two characters can be correctly encoded in Latin-2, Windows-1250 and Unicode. Before Unicode became common in due east-mail clients, e-mails containing Hungarian text often had the letters ő and ű corrupted, sometimes to the point of unrecognizability. It is mutual to reply to an email rendered unreadable (see examples beneath) by graphic symbol mangling (referred to as "betűszemét", pregnant "letter garbage") with the phrase "Árvíztűrő tükörfúrógép", a nonsense phrase (literally "Flood-resistant mirror-drilling motorcar") containing all accented characters used in Hungarian.
Examples [edit]
| Source encoding | Target encoding | Effect | Occurrence |

| Hungarian example | ÁRVÍZTŰRŐ TÜKÖRFÚRÓGÉP árvíztűrő tükörfúrógép | Characters in red are incorrect and exercise not lucifer the top-left case. | |

Delight note that minor-case letters are mainly correct, exception with ő (ï) and ű (√). Ü/ü is correct because CP 852 was made compatible with German. Nowadays occurs mainly on printed prescriptions and cheques. |
| CWI-ii | CP 437 | ÅRVìZTÿRº TÜKÖRFùRòGÉP árvíztûrô tükörfúrógép | The CWI-2 encoding was designed so that the text remains fairly well-readable even if the display or printer uses the default CP 437 encoding.

Polish [edit]
Prior to the creation of ISO 8859-two in 1987, users of diverse computing platforms used their own grapheme encodings such every bit AmigaPL on Amiga, Atari Club on Atari ST and Masovia, IBM CP852, Mazovia and Windows CP1250 on IBM PCs. Smooth companies selling early DOS computers created their own mutually-incompatible ways to encode Shine characters and but reprogrammed the EPROMs of the video cards (typically CGA, EGA, or Hercules) to provide hardware code pages with the needed glyphs for Polish—arbitrarily located without reference to where other computer sellers had placed them.
The situation began to improve when, after pressure from academic and user groups, ISO 8859-2 succeeded as the "Cyberspace standard" with limited support of the dominant vendors' software (today largely replaced by Unicode). With the numerous problems acquired by the variety of encodings, fifty-fifty today some users tend to refer to Polish diacritical characters as krzaczki ([kshach-kih], lit. "piddling shrubs").
Russian and other Cyrillic alphabets [edit]
Mojibake may exist colloquially chosen krakozyabry ( кракозя́бры [krɐkɐˈzʲæbrɪ̈]) in Russian, which was and remains complicated by several systems for encoding Cyrillic.[6] The Soviet Matrimony and early Russian Federation developed KOI encodings ( Kod Obmena Informatsiey , Код Обмена Информацией , which translates to "Code for Data Substitution"). This began with Cyrillic-only 7-fleck KOI7, based on ASCII but with Latin and some other characters replaced with Cyrillic letters. Then came 8-flake KOI8 encoding that is an ASCII extension which encodes Cyrillic letters only with high-bit set octets respective to 7-bit codes from KOI7. It is for this reason that KOI8 text, fifty-fifty Russian, remains partially readable after stripping the eighth bit, which was considered equally a major advantage in the age of 8BITMIME-unaware email systems. For example, words " Школа русского языка " shkola russkogo yazyka , encoded in KOI8 and then passed through the high bit stripping procedure, end up rendered as "[KOLA RUSSKOGO qZYKA". Somewhen KOI8 gained dissimilar flavors for Russian and Bulgarian (KOI8-R), Ukrainian (KOI8-U), Belarusian (KOI8-RU) and fifty-fifty Tajik (KOI8-T).
Meanwhile, in the West, Lawmaking page 866 supported Ukrainian and Belarusian equally well as Russian/Bulgarian in MS-DOS. For Microsoft Windows, Code Page 1251 added back up for Serbian and other Slavic variants of Cyrillic.
Most recently, the Unicode encoding includes code points for practically all the characters of all the world'due south languages, including all Cyrillic characters.
Earlier Unicode, it was necessary to match text encoding with a font using the same encoding system. Failure to do this produced unreadable gibberish whose specific appearance varied depending on the exact combination of text encoding and font encoding. For case, attempting to view not-Unicode Cyrillic text using a font that is express to the Latin alphabet, or using the default ("Western") encoding, typically results in text that consists almost entirely of vowels with diacritical marks. (KOI8 " Библиотека " ( biblioteka , library) becomes "âÉÂÌÉÏÔÅËÁ".) Using Windows codepage 1251 to view text in KOI8 or vice versa results in garbled text that consists mostly of capital letters (KOI8 and codepage 1251 share the same ASCII region, only KOI8 has uppercase letters in the region where codepage 1251 has lowercase, and vice versa). In general, Cyrillic gibberish is symptomatic of using the wrong Cyrillic font. During the early years of the Russian sector of the Globe Broad Web, both KOI8 and codepage 1251 were mutual. As of 2017, one tin can withal encounter HTML pages in codepage 1251 and, rarely, KOI8 encodings, as well as Unicode. (An estimated ane.7% of all web pages worldwide – all languages included – are encoded in codepage 1251.[7]) Though the HTML standard includes the ability to specify the encoding for any given web folio in its source,[8] this is sometimes neglected, forcing the user to switch encodings in the browser manually.
In Bulgarian, mojibake is often chosen majmunica ( маймуница ), meaning "monkey's [alphabet]". In Serbian, it is called đubre ( ђубре ), significant "trash". Unlike the former USSR, Due south Slavs never used something like KOI8, and Lawmaking Page 1251 was the ascendant Cyrillic encoding at that place before Unicode. Therefore, these languages experienced fewer encoding incompatibility troubles than Russian. In the 1980s, Bulgarian computers used their own MIK encoding, which is superficially like to (although incompatible with) CP866.

| MS-DOS 855 | ISO 8859-1 | Æá ÆÖóÞ¢áñ |
| KOI8-R | ISO 8859-1 | ëÒÁËÏÚÑÂÒÙ |
| UTF-8 | KOI8-R | п я─п╟п╨п╬п╥я▐п╠я─я▀ |
Yugoslav languages [edit]
Croatian, Bosnian, Serbian (the dialects of the Yugoslav Serbo-Croatian language) and Slovene add to the bones Latin alphabet the messages š, đ, č, ć, ž, and their capital counterparts Š, Đ, Č, Ć, Ž (merely č/Č, š/Š and ž/Ž in Slovenian; officially, although others are used when needed, by and large in foreign names, as well). All of these letters are defined in Latin-2 and Windows-1250, while only some (š, Š, ž, Ž, Đ) exist in the usual Os-default Windows-1252, and are there because of another languages.
Although Mojibake tin occur with any of these characters, the letters that are not included in Windows-1252 are much more than prone to errors. Thus, fifty-fifty nowadays, "šđčćž ŠĐČĆŽ" is often displayed as "šðèæž ŠÐÈÆŽ", although ð, è, æ, È, Æ are never used in Slavic languages.
When bars to basic ASCII (most user names, for example), common replacements are: š→s, đ→dj, č→c, ć→c, ž→z (capital forms analogously, with Đ→Dj or Đ→DJ depending on word case). All of these replacements innovate ambiguities, and then reconstructing the original from such a form is usually washed manually if required.
The Windows-1252 encoding is of import because the English language versions of the Windows operating system are most widespread, non localized ones.[ commendation needed ] The reasons for this include a relatively modest and fragmented market place, increasing the price of high quality localization, a high degree of software piracy (in turn caused by high cost of software compared to income), which discourages localization efforts, and people preferring English versions of Windows and other software.[ citation needed ]
The drive to differentiate Croatian from Serbian, Bosnian from Croatian and Serbian, and now fifty-fifty Montenegrin from the other iii creates many problems. In that location are many different localizations, using different standards and of different quality. At that place are no mutual translations for the vast corporeality of figurer terminology originating in English. In the end, people apply adopted English words ("kompjuter" for "computer", "kompajlirati" for "compile," etc.), and if they are unaccustomed to the translated terms may not understand what some choice in a menu is supposed to do based on the translated phrase. Therefore, people who sympathize English language, too every bit those who are accepted to English terminology (who are nigh, because English terminology is also more often than not taught in schools because of these issues) regularly choose the original English versions of non-specialist software.
When Cyrillic script is used (for Macedonian and partially Serbian), the problem is similar to other Cyrillic-based scripts.
Newer versions of English Windows allow the lawmaking page to exist inverse (older versions crave special English versions with this support), but this setting tin be and oft was incorrectly set. For example, Windows 98 and Windows Me tin exist prepare to most not-correct-to-left single-byte code pages including 1250, only but at install time.
Caucasian languages [edit]
The writing systems of certain languages of the Caucasus region, including the scripts of Georgian and Armenian, may produce mojibake. This trouble is particularly acute in the case of ArmSCII or ARMSCII, a set of obsolete graphic symbol encodings for the Armenian alphabet which have been superseded by Unicode standards. ArmSCII is not widely used because of a lack of back up in the computer industry. For example, Microsoft Windows does not support it.
Asian encodings [edit]
Another blazon of mojibake occurs when text is erroneously parsed in a multi-byte encoding, such as i of the encodings for E Asian languages. With this kind of mojibake more i (typically two) characters are corrupted at once, due east.g. "k舐lek" ( kärlek ) in Swedish, where " är " is parsed every bit "舐". Compared to the above mojibake, this is harder to read, since letters unrelated to the problematic å, ä or ö are missing, and is especially problematic for brusk words starting with å, ä or ö such equally "än" (which becomes "舅"). Since 2 letters are combined, the mojibake also seems more random (over fifty variants compared to the normal three, not counting the rarer capitals). In some rare cases, an entire text string which happens to include a pattern of detail word lengths, such as the sentence "Bush hid the facts", may be misinterpreted.
Vietnamese [edit]
In Vietnamese, the phenomenon is called chữ ma , loạn mã can occur when calculator try to encode diacritic graphic symbol defined in Windows-1258, TCVN3 or VNI to UTF-8. Chữ ma was common in Vietnam when user was using Windows XP figurer or using cheap mobile telephone.
| Example: | Trăm năm trong cõi người ta (Truyện Kiều, Nguyễn Du) | |
|---|---|---|
| Original encoding | Target encoding | Event |
| Windows-1258 | UTF-eight | Trăm northăthou trong cõi ngÆ°á»i ta |
| TCVN3 | UTF-8 | Tr¨m northward¨m trong câi ngêi ta |
| VNI (Windows) | UTF-8 | Traêm northwardaêm trong coõi ngöôøi ta |
Japanese [edit]
In Japanese, the same phenomenon is, as mentioned, called mojibake ( 文字化け ). It is a item problem in Japan due to the numerous different encodings that exist for Japanese text. Aslope Unicode encodings like UTF-8 and UTF-16, there are other standard encodings, such as Shift-JIS (Windows machines) and EUC-JP (UNIX systems). Mojibake, as well as being encountered by Japanese users, is also oft encountered by non-Japanese when attempting to run software written for the Japanese market place.
Chinese [edit]
In Chinese, the same phenomenon is chosen Luàn mǎ (Pinyin, Simplified Chinese 乱码 , Traditional Chinese 亂碼 , meaning 'chaotic lawmaking'), and can occur when computerised text is encoded in ane Chinese character encoding but is displayed using the wrong encoding. When this occurs, it is often possible to fix the event by switching the character encoding without loss of data. The situation is complicated because of the being of several Chinese graphic symbol encoding systems in utilize, the most common ones beingness: Unicode, Big5, and Guobiao (with several backward compatible versions), and the possibility of Chinese characters existence encoded using Japanese encoding.
It is easy to identify the original encoding when luanma occurs in Guobiao encodings:
| Original encoding | Viewed as | Upshot | Original text | Note |
|---|---|---|---|---|
| Big5 | GB | ?T瓣в变巨肚 | 三國志曹操傳 | Garbled Chinese characters with no hint of original meaning. The ruby-red character is non a valid codepoint in GB2312. |
| Shift-JIS | GB | 暥帤壔偗僥僗僩 | 文字化けテスト | Kana is displayed as characters with the radical 亻, while kanji are other characters. Most of them are extremely uncommon and not in applied employ in modern Chinese. |

An additional problem is acquired when encodings are missing characters, which is common with rare or blowsy characters that are still used in personal or place names. Examples of this are Taiwanese politicians Wang Chien-shien (Chinese: 王建煊; pinyin: Wáng Jiànxuān )'s "煊", Yu Shyi-kun (simplified Chinese: 游锡堃; traditional Chinese: 游錫堃; pinyin: Yóu Xíkūn )'s "堃" and singer David Tao (Chinese: 陶喆; pinyin: Táo Zhé )'s "喆" missing in Big5, ex-PRC Premier Zhu Rongji (Chinese: 朱镕基; pinyin: Zhū Róngjī )'due south "镕" missing in GB2312, copyright symbol "©" missing in GBK.[9]
Newspapers have dealt with this problem in various ways, including using software to combine 2 existing, similar characters; using a picture of the personality; or but substituting a homophone for the rare character in the promise that the reader would be able to brand the correct inference.
Indic text [edit]
A similar effect can occur in Brahmic or Indic scripts of South asia, used in such Indo-Aryan or Indic languages as Hindustani (Hindi-Urdu), Bengali, Punjabi, Marathi, and others, even if the character gear up employed is properly recognized by the application. This is considering, in many Indic scripts, the rules by which individual letter symbols combine to create symbols for syllables may not be properly understood past a computer missing the advisable software, even if the glyphs for the private letter of the alphabet forms are available.
I example of this is the erstwhile Wikipedia logo, which attempts to evidence the character analogous to "wi" (the kickoff syllable of "Wikipedia") on each of many puzzle pieces. The puzzle piece meant to bear the Devanagari grapheme for "wi" instead used to display the "wa" character followed by an unpaired "i" modifier vowel, hands recognizable as mojibake generated by a computer not configured to brandish Indic text.[10] The logo as redesigned as of May 2010[ref] has stock-still these errors.
The idea of Evidently Text requires the operating system to provide a font to display Unicode codes. This font is different from OS to OS for Singhala and it makes orthographically incorrect glyphs for some letters (syllables) across all operating systems. For instance, the 'reph', the short class for 'r' is a diacritic that commonly goes on height of a plain letter. However, it is wrong to keep elevation of some letters similar 'ya' or 'la' in specific contexts. For Sanskritic words or names inherited by modern languages, such every bit कार्य, IAST: kārya, or आर्या, IAST: āryā, information technology is apt to put it on top of these letters. Past dissimilarity, for like sounds in modern languages which result from their specific rules, information technology is non put on top, such every bit the discussion करणाऱ्या, IAST: karaṇāryā, a stalk form of the common discussion करणारा/री, IAST: karaṇārā/rī, in the Marathi language.[xi] Only it happens in most operating systems. This appears to be a fault of internal programming of the fonts. In Mac Os and iOS, the muurdhaja l (dark l) and 'u' combination and its long form both yield incorrect shapes.[ citation needed ]
Some Indic and Indic-derived scripts, almost notably Lao, were not officially supported by Windows XP until the release of Vista.[12] Notwithstanding, various sites have made gratis-to-download fonts.
Burmese [edit]
Due to Western sanctions[13] and the late inflow of Burmese linguistic communication support in computers,[14] [15] much of the early Burmese localization was homegrown without international cooperation. The prevailing means of Burmese back up is via the Zawgyi font, a font that was created equally a Unicode font but was in fact simply partially Unicode compliant.[15] In the Zawgyi font, some codepoints for Burmese script were implemented as specified in Unicode, but others were non.[sixteen] The Unicode Consortium refers to this as advertisement hoc font encodings.[17] With the advent of mobile phones, mobile vendors such as Samsung and Huawei merely replaced the Unicode compliant system fonts with Zawgyi versions.[14]
Due to these ad hoc encodings, communications between users of Zawgyi and Unicode would render equally garbled text. To get around this issue, content producers would make posts in both Zawgyi and Unicode.[18] Myanmar government has designated i October 2019 as "U-Solar day" to officially switch to Unicode.[13] The total transition is estimated to accept two years.[nineteen]
African languages [edit]
In certain writing systems of Africa, unencoded text is unreadable. Texts that may produce mojibake include those from the Horn of Africa such as the Ge'ez script in Ethiopia and Eritrea, used for Amharic, Tigre, and other languages, and the Somali linguistic communication, which employs the Osmanya alphabet. In Southern Africa, the Mwangwego alphabet is used to write languages of Republic of malaŵi and the Mandombe alphabet was created for the Democratic Congo-brazzaville, only these are not generally supported. Various other writing systems native to West Africa present similar problems, such as the Due north'Ko alphabet, used for Manding languages in Guinea, and the Vai syllabary, used in Liberia.
Arabic [edit]
Another affected linguistic communication is Arabic (see beneath). The text becomes unreadable when the encodings do not lucifer.

The examples in this article do not accept UTF-eight as browser setting, because UTF-eight is easily recognisable, then if a browser supports UTF-eight it should recognise it automatically, and non effort to interpret something else as UTF-viii.
