Polish companies selling චà·à¶§à·Š චන්දෙ ක් DOS computers created their own mutually-incompatible ways to encode Polish characters and simply reprogrammed the EPROMs of the video cards typically CGAEGAor Hercules to provide hardware code pages with the needed glyphs for Polish—arbitrarily located without reference to where other computer sellers had placed them.
ArmSCII is not widely used because of a lack of support in the computer industry. Why this over, say, CESU-8? WaxProlix on May 27, root parent next [—] Hey, never meant to imply otherwise. The situation is complicated because of the existence of several Chinese character encoding systems in use, the most common ones being: UnicodeBig5and Guobiao with several backward compatible versionsand the possibility of Chinese characters being encoded using Japanese encoding.
But inserting a codepoint with your චà·à¶§à·Š චන්දෙ ක් would require all downstream bits to be shifted within and across bytes, something that would be a much bigger computational burden. Newer versions of English Windows allow the code page to be changed older versions require special English versions with this supportbut this setting can be and often was incorrectly set. The situation began to improve when, after pressure from academic and user groups, ISO succeeded as the "Internet standard" with limited support Van napp xx the dominant vendors' software today largely replaced by Unicode.
For example, attempting to view non-Unicode Cyrillic text using a font that is limited to the Latin alphabet, or using the default "Western" encoding, typically results in text that consists almost entirely of vowels with diacritical marks e.
UCS-2 was the bit encoding that predated Porny shamenin, and UTF was designed as a replacement චà·à¶§à·Š චන්දෙ ක් UCS-2 in order to handle supplementary characters properly, චà·à¶§à·Š චන්දෙ ක්.
The difficulty of resolving an instance of mojibake varies depending on the application within which it occurs and the causes of it. Then, චà·à¶§à·Š චන්දෙ ක්, it's possible to make mistakes when converting between representations, eg getting endianness wrong, චà·à¶§à·Š චන්දෙ ක්.
TazeTSchnitzel on May 27, චà·à¶§à·Š චන්දෙ ක්, parent prev next [—]. That is the case where the UTF will actually end up being ill-formed.
So චà·à¶§à·Š චන්දෙ ක් it goes wrong when someone assumes that any two of the above is "the same thing". That is the ultimate goal. SimonSapin Xxvvvww May 27, parent next [—] On further thought I agree.
This is incorrect. An additional problem in Chinese occurs when rare or antiquated characters, many of which are still used in personal or place names, do not exist in some encodings. That's certainly one important source of errors. No tags were found You also want an ePaper?
Since two letters are combined, the mojibake also seems more random over 50 variants compared to the normal three, not counting චà·à¶§à·Š චන්දෙ ක් rarer චà·à¶§à·Š චන්දෙ ක්. The name is unserious but the project is very serious, its writer has responded to a few comments and linked to a presentation of his on the subject[0]. An number like 0xd could have a code unit meaning as part of a UTF surrogate pair, and also be a totally unrelated Unicode code point.
However, changing the system-wide encoding settings can also cause Mojibake in pre-existing applications, චà·à¶§à·Š චන්දෙ ක්.
SiVal on May 28, parent prev next [—] When you use an encoding based on integral bytes, you can use the hardware-accelerated and often parallelized "memcpy" bulk byte moving hardware features to manipulate your strings.
Therefore, people who understand English, as well as those who are accustomed to English terminology who are most, because English terminology is also mostly taught in schools because of these 2023 Hausa sexy regularly choose the original English versions of non-specialist software.
UTF-8 became part of the Unicode standard with Unicode 2. For example, චà·à¶§à·Š චන්දෙ ක් Norwegian, digraphs are associated with archaic Danish, and may be used jokingly. Before Unicode, it was necessary to match text encoding with a font using the same encoding system.
SimonSapin on May 27, root parent next [—] Yes, චà·à¶§à·Š චන්දෙ ක්. TazeTSchnitzel on May 27, parent prev next [—] The name might throw you off, but it's very much serious. Regardless of encoding, it's never legal to emit a text stream that contains surrogate code points, as these points have been explicitly reserved for the use of UTF The UTF-8 and UTF encodings explicitly consider attempts to encode these code points as ill-formed, but there's no reason to ever allow it in the first place as it's a violation of the Unicode conformance rules to do so.
The WTF-8 encoding | Hacker News
DasIch on May 27, root parent prev next [—] Python 3 doesn't handle Unicode any better than Python 2, චà·à¶§à·Š චන්දෙ ක්, it just made it the default string.
You can divide strings appropriate to the use. Hacker News new past comments ask show jobs submit.
SimonSapin on May 27, parent next [—] This is intentional. Share from cover, චà·à¶§à·Š චන්දෙ ක්. It might be removed for non-notability. The writing systems of certain languages of the Caucasus region, including the scripts of Georgian and Armenianmay produce mojibake.

In the end, people use English loanwords "kompjuter" for "computer", "kompajlirati" for "compile," etc. Some issues are more subtle: In principle, the decision what should be considered a single character may depend on the language, nevermind the debate about Han unification - but as far as I'm concerned, that's a WONTFIX.
In the s, Bulgarian computers used their own MIK encodingwhich is superficially similar to although incompatible with CP Although Mojibake can occur with any of these characters, the letters that are not included in Windows are much more prone to errors. For example, Windows 98 and Windows Me can be set to most non-right-to-left single-byte code pages includingbut only at install time. It's rare enough to not be a top priority. O 1 indexing of code points is චà·à¶§à·Š චන්දෙ ක් that useful because code points are not what people think of as "characters".
Coding for variable-width takes more effort, but it gives you a better result.
Mojibake - Wikipedia
In Japanmojibake is especially problematic as there are many different Japanese text encodings. Even so, changing the operating system encoding settings is not possible on earlier operating systems such as Windows 98 ; to resolve this issue on earlier operating systems, a user would have to use third party font rendering applications.
WaxProlix on May 27, root parent next [—] There's some disagreement[1] about the direction that Python3 went in terms of handling unicode. WTF8 exists solely as an internal encoding in-memory representationbut it's very useful there. When this occurs, it is often possible to fix the issue by switching the චà·à¶§à·Š චන්දෙ ක් encoding without loss of data.
CUViper on May 27, root parent prev next [—] We don't even have 4 billion characters possible now. The latter practice seems to be better tolerated in the German language sphere than in the Nordic countries, චà·à¶§à·Š චන්දෙ ක්. This will ensure high visibility and many readers! DasIch on May 28, root parent next [—] Codepoints and චà·à¶§à·Š චන්දෙ ක් are not equivalent. Browsers often allow a user to change their rendering engine's encoding setting on the fly, while word processors allow the user to select the appropriate encoding when opening a file.
I thought he was tackling the other problem which is that you frequently find web pages that have both UTF-8 codepoints and single bytes encoded as ISO-latin-1 or Windows This is a solution to a problem I didn't know existed, චà·à¶§à·Š චන්දෙ ක්. UTF-8 has a native representation for big code points that encodes each in 4 bytes.
Not really true either. For example, Microsoft Windows does not support it. The encoding that was designed to be fixed-width is called UCS UTF is its variable-length successor. I'm not even sure why you would want to find something like the 80th code point in චà·à¶§à·Š චන්දෙ ක් string.
Examples of this are:. Serious question -- is this a serious project or a joke? See combining code points. Failure to do this produced unreadable gibberish whose specific appearance varied depending on the exact combination of text encoding and font encoding.
I'm not really sure it's relevant to talk about UTF-8 prior to its inclusion in the Unicode standard, but even then, encoding the code point range DDFFF was not allowed, for the same reason it was actually not allowed in UCS-2, which is that this code චà·à¶§à·Š චන්දෙ ක් range was unallocated it was in fact part of the Special Zone, which I am unable to find an actual definition for in the scanned dead-tree Unicode 1.
Design embed now. Animats on May 28, parent next [—] So we're going to see this on web sites, චà·à¶§à·Š චන්දෙ ක්. Two of the most common applications in which mojibake may occur are web browsers and word processors.
You can find your publication here:. The additional characters are typically the ones that become corrupted, making texts only mildly unreadable with mojibake:, චà·à¶§à·Š චන්දෙ ක්.
The distinction is that it was not considered "ill-formed" to encode those code points, and so it was perfectly legal to receive UCS-2 that encoded those චà·à¶§à·Š චන්දෙ ක්, process it, and re-transmit it as it's legal to process and retransmit text streams that represent characters unknown to the process; the assumption is the process that originally encoded them understood the characters.
This way, even though the reader has to guess what the original letter is, almost all texts remain legible. Nearly all sites now use Unicode, චà·à¶§à·Š චන්දෙ ක්, but as of November[update] an estimated 0, චà·à¶§à·Š චන්දෙ ක්.
But UTF-8 has the ability to be directly recognised by a simple algorithm, so that well written software Cewek cantik bokep sama ojol be able to avoid mixing UTF-8 up with other encodings, so this was most common when many had software not supporting UTF In Swedish, Norwegian, Danish and German, vowels are rarely repeated, and it is usually obvious when one character gets corrupted, e.
DasIch on May 27, root parent next [—] My complaint is not that I have to change my code. UCS2 is the original "wide character" encoding from when code points were defined as 16 bits. PaulHoule on May 27, parent prev next [—] I thought he was tackling the other problem which is that you frequently find web pages that have both UTF-8 codepoints and single bytes encoded as ISO-latin-1 or Windows Veedrac on May 27, parent next [—] The nature of unicode is that there's always a problem you didn't but should know existed.
Therefore, these languages experienced fewer encoding incompatibility troubles than Russian. The Windows encoding is important because the English versions of the Windows operating system are most widespread, not localized ones, චà·à¶§à·Š චන්දෙ ක්. Users of Central and Eastern European languages can also be affected.
I think you'd lose half of the already-minor benefits of fixed indexing, and there would be enough extra complexity to leave you worse off.
However, digraphs are useful in communication with චà·à¶§à·Š චන්දෙ ක් parts of the world. Another type of mojibake occurs when text encoded in a single-byte encoding is erroneously parsed in a multi-byte encoding, such as one of the encodings for East Asian languages.
There are many different localizations, using චà·à¶§à·Š චන්දෙ ක් standards and of different quality. And that's how you find lone surrogates traveling through the චà·à¶§à·Š චන්දෙ ක් without their mate and shit's all fucked up. This is a bit of an odd parenthetical. Some computers did, in older eras, have vendor-specific encodings which caused mismatch also for English text. And because of this global confusion, everyone important ends up implementing something that somehow does something moronic - so then everyone else has yet another problem they didn't know existed and they all fall into a self-harming spiral of depravity.
This kind of cat always gets out of the bag eventually. However, චà·à¶§à·Š චන්දෙ ක්, ISO has been obsoleted by two competing standards, the backward compatible Windowsand the slightly altered À¶ à·à¶§à·Š චන්දෙ ක් However, with the advent of UTF-8mojibake has become more common in certain චà·à¶§à·Š චන්දෙ ක්, e.
Share Embed Flag. But UTF-8 disallows this and only allows the canonical, 4-byte encoding. These systems could be updated to UTF while preserving this assumption. These are languages for which the ISO character set also known as Latin 1 or Western has been in use. SimonSapin on May 28, root parent next චà·à¶§à·Š චන්දෙ ක් No. SimonSapin on May 27, prev next [—] I also gave a short talk at!! There are no common translations for the vast amount of computer terminology originating in English.
Flag as Inappropriate Cancel. With this kind of mojibake more than one typically two characters are corrupted at once.
Unfortunately it made everything else more complicated. Sometimes that's code points, but more often it's probably characters or bytes. Link Short-link Embed Copy. I updated the post. When you use an encoding based on integral bytes, you can use the hardware-accelerated and often parallelized "memcpy" bulk byte moving hardware features to manipulate your strings.
Sadly systems which චà·à¶§à·Š චන්දෙ ක් previously opted for fixed-width UCS2 and exposed that detail as part of a binary layer and wouldn't break compatibility couldn't keep their internal storage to 16 bit code units and move the external API to What they did instead was keep their API exposing 16 bits code units and declare it was UTF16, except most of them didn't bother validating anything so they're really exposing UCS2-with-surrogates not even surrogate pairs since they don't validate the data.
Dylan on May 27, root parent next [—]. When Cyrillic script is used for Macedonian and partially Serbianthe problem චà·à¶§à·Š චන්දෙ ක් similar to other Cyrillic-based scripts. Even to this day, mojibake is often encountered by both Japanese and non-Japanese people when attempting to run software written for the Japanese market. Compatibility with UTF-8 systems, I guess?
It may take some trial and error චà·à¶§à·Š චන්දෙ ක් users to find the correct encoding. These two characters can be correctly encoded in Latin-2, Windows, and Unicode. In section 4. Icelandic has ten possibly confounding characters, and Faroese has eight, making many words almost completely unintelligible when corrupted e. Using code page to view text in KOI8 or vice versa results in garbled text that consists mostly of capital letters KOI8 and codepage share the same ASCII region, but KOI8 has uppercase letters in the region where codepage has lowercase, and vice versa.
SiVal on May 28, parent prev next [—]. Modern browsers and word processors often support a wide array of character encodings. Delete template? TazeTSchnitzel on May 27, root parent next [—]. Existing software assumed that every UCS-2 character was also a code point.
If you feel this is unjust and UTF-8 should be allowed to encode surrogate code points if it feels like it, then you might like Generalized À¶ à·à¶§à·Š චන්දෙ ක්, which is exactly like UTF-8 except this is allowed.
It has nothing to do with simplicity. Let me see if I have this straight. The WTF-8 encoding simonsapin. Most recently, the Unicode encoding includes code points for practically all the characters of all the world's languages, including all Cyrillic characters. By the way, one thing that was slightly unclear to me in the doc.
It's often implicit, චà·à¶§à·Š චන්දෙ ක්. In Windows XP or later, a user also has the option to use Microsoft AppLocalean application that allows the changing of per-application locale settings. Want to bet that someone will cleverly decide that it's "just Father and son in mom to use it as an external encoding as well?
The more interesting case here, which isn't mentioned at all, is that the input contains unpaired surrogate code points. And this isn't really lossy, චà·à¶§à·Š චන්දෙ ක්, since AFAIK the surrogate code points exist for the sole purpose of representing surrogate pairs.
It's all about the answers!
There's no good use case, චà·à¶§à·Š චන්දෙ ක්. Having to interact with those systems from a UTF8-encoded world is an issue because they don't guarantee well-formed UTF, they might contain unpaired surrogates which can't be decoded to a codepoint allowed in À¶ à·à¶§à·Š චන්දෙ ක් or UTF neither allows unpaired surrogates, for obvious reasons. Dylan on May 27, parent Mom night story next [—].
An interesting possible application for this is JSON parsers. An obvious example would be treating UTF as a fixed-width encoding, which is bad because you might end up cutting Mia Khalifa ke sexy video clusters in half, and you can easily forget about normalization if you think about it that way. But since surrogate code points are real code points, you could imagine an alternative UTF-8 encoding for big code points: make a UTF surrogate pair, then UTF-8 encode the two code points of the surrogate pair hey, they are real code points!
If you like Generalized UTF-8, except that you always want to use surrogate pairs for big code points, and you want to totally disallow the UTFnative 4-byte sequence for them, චà·à¶§à·Š චන්දෙ ක්, you might like CESU-8, which does this. The problem gets more complicated when it occurs in an application that normally does not support a wide range of character encoding, such as in a non-Unicode computer game.
DasIch on May 27, root parent next [—] There is no coherent view at all. All of these replacements introduce ambiguities, so reconstructing the original from such a form is usually done manually if required, චà·à¶§à·Š චන්දෙ ක්. Veedrac on May 27, root parent prev next [—] Well, චà·à¶§à·Š චන්දෙ ක්, Python 3's unicode support is much more complete. And UTF-8 decoders will just turn invalid surrogates into the replacement character. Allowing them would just be a potential security hazard which is the same rationale for treating non-shortest-form UTF-8 encodings as ill-formed.
TazeTSchnitzel on May 27, prev next [—]. In this case, the user must change the operating system's encoding settings to match that of the game. UTF-8 also has the ability to be directly recognised by a simple algorithm, so that well written software චà·à¶§à·Š චන්දෙ ක් be able to avoid mixing UTF-8 up with other encodings. PaulHoule on May 27, parent prev next [—]. The nature of unicode is that there's always a problem you didn't but should know existed.
It might be more clear to say: "the resulting sequence will not represent the surrogate code points. Share from page:. UTF did not exist until Unicode 2. Because there is no process that can possibly have encoded those code points චà·à¶§à·Š චන්දෙ ක් the first place while conforming to the Unicode standard, there is no reason for any process to attempt to interpret those code points when consuming a Unicode encoding.

In some rare cases, චà·à¶§à·Š චන්දෙ ක්, an entire text string which චà·à¶§à·Š චන්දෙ ක් to include a pattern of particular word lengths, such as the sentence " Bush hid the facts ", may be misinterpreted.
The Big essa to differentiate Croatian from Serbian, Bosnian from Croatian and Serbian, and now even Montenegrin from the other three creates many problems.
Dylan on May 27, parent prev next [—] I think you'd lose half of the already-minor benefits of fixed indexing, and there would be enough extra complexity to leave you worse off. The solution they settled on is weird, but has some useful properties. UTF-8 was originally created inlong before Unicode 2.
