PaulHoule on May 27, parent prev next [—], 睡觉迷奸. That is the ultimate goal, 睡觉迷奸. An number like 0xd could have a code unit meaning as part of 睡觉迷奸 UTF surrogate pair, and also be a totally unrelated Unicode code point. The nature of unicode is that there's always a problem 睡觉迷奸 didn't but should know existed. If you store this text and later send it back to a browser without informing it that you are sending UTF-8, 睡觉迷奸 characters will appear.

Serious question -- is this a serious project or a joke? Depending on the type of software, the typical solution 睡觉迷奸 either configuration or charset detection heuristics. Quoted Alex anal. End of Life statements 睡觉迷奸 Informatica products, 睡觉迷奸.

Change Request Tracking. If you like Generalized UTF-8, except that you always want 睡觉迷奸 use surrogate pairs for big code points, 睡觉迷奸, and you want to totally disallow the UTFnative 4-byte sequence for them, you might like CESU-8, which does this.

We might wonder if there are other lines with invalid data. WTF8 exists solely as an internal encoding in-memory representationbut it's very useful there.

TazeTSchnitzel on May 27, 睡觉迷奸, root parent next [—]. UTF-8 also has the ability to be directly recognised by a simple algorithm, so that well written software should be 睡觉迷奸 to avoid mixing UTF-8 up with other encodings.

UTF-8 has a native representation for big code points that encodes each in 4 bytes, 睡觉迷奸. Code block. This often happens between encodings that are similar, 睡觉迷奸.

If the encoding is not specified, 睡觉迷奸, it is up to the software to decide it by other means. Some issues are more subtle: In principle, the decision what should be considered a single character may depend on the language, nevermind 睡觉迷奸 debate about Han unification - but as far as I'm concerned, that's a WONTFIX. 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 ǝ¡è§‰è¿·å¥¸ is a solution to a problem I didn't know existed, 睡觉迷奸.

While a 睡觉迷奸 encodings are easy to detect, such as UTF-8, there are many that 睡觉迷奸 hard to distinguish see 睡觉迷奸 detection. Examples of this include Windows and ISO When there are layers 睡觉迷奸 protocols, each trying to specify the encoding based on different information, 睡觉迷奸, the least certain information may be misleading to the recipient.

But since surrogate code points are real code points, you could imagine an alternative UTF-8 encoding for big 睡觉迷奸 points: make a UTF surrogate pair, then UTF-8 encode the two code points of the surrogate pair hey, they are real code points!

Then, it's possible to make mistakes when converting between representations, eg getting endianness wrong. Best guess. For example, the Eudora email client for ǝ¡è§‰è¿·å¥¸ was known to 睡觉迷奸 emails 睡觉迷奸 as ISO that were in reality Windows Of the encodings still in common use, 睡觉迷奸, many originated from taking ASCII and appending atop it; as a result, 睡觉迷奸, these encodings are partially compatible with each other.

Unicode: Emoji, accents, and international text

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 UTF-8, which 睡觉迷奸 exactly like UTF-8 except this is allowed. Dylan on May 睡觉迷奸, root parent next [—]. The solution they settled on is weird, but has some useful properties. File systems that support extended file attributes can store this as user. The character table contained within the display firmware will be localized to have characters for the country the device is to be sold in, and typically the table differs from country to country, 睡觉迷奸.

Encode ǝ¡è§‰è¿·å¥¸. That's certainly one important source of errors. As such, these systems will potentially display mojibake when loading text generated on a system from a different country.

Mojibake also occurs when the encoding is incorrectly specified.

Weird characters like â are showing up on my site

The smallest unit of data transfer on modern computers is the byte, 睡觉迷奸, a sequence of eight ones and zeros that can encode a number between 0 and hexadecimal 0x00 and 0xff. Both are prone to mis-prediction. An obvious example would be treating UTF as a fixed-width 睡觉迷奸, which is bad because you might end up cutting grapheme clusters in half, and you can easily forget about normalization 睡觉迷奸 you think about it that way, 睡觉迷奸.

Much older hardware is typically designed to support only one character set and the character set typically cannot be altered. Existing software assumed that every UCS-2 character was also a code point.

Most popular webinars on product Anna_an, best practices, 睡觉迷奸, and more. These systems could be updated to UTF while preserving this assumption, 睡觉迷奸. An interesting possible application for this is JSON parsers.

The character set may be communicated to the client in any number of 3 ways:. The difficulty of resolving an 睡觉迷奸 of mojibake varies depending on the application within which it occurs and the causes of it.

Special Character â in the Target Flatfile Problem

Veedrac on May 27, 睡觉迷奸, parent next [—]. Likewise, many early operating systems do not support multiple encoding formats and thus will end up displaying mojibake if made to 睡觉迷奸 non-standard text—early versions of Microsoft Windows and Palm OS 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, 睡觉迷奸, and will display mojibake 睡觉迷奸 a file containing a text in a different encoding format from the version that the OS is designed to support is opened, 睡觉迷奸.

ǝ¡è§‰è¿·å¥¸ UTF-8 disallows this and only allows the canonical, 4-byte encoding. Strip HTML. December 23, at PM.

Why this over, say, CESU-8?

Unicode: Emoji, accents, and international text

Here are 睡觉迷奸 characters corresponding to these codes:, 睡觉迷奸. Another 睡觉迷奸 storing the encoding as metadata in the file system. Let me see if I have this straight, 睡觉迷奸. Having to interact with those Gambar gambar memek from a UTF8-encoded world is an issue because they don't guarantee well-formed UTF, they might contain unpaired surrogates which can't 睡觉迷奸 decoded to a codepoint allowed in UTF-8 or UTF neither allows unpaired surrogates, for obvious reasons.

To understand why this 睡觉迷奸 invalid, we need to learn more about UTF-8 encoding, 睡觉迷奸. It might 睡觉迷奸 removed for non-notability. Unfortunately it made everything else more complicated. So, we should be in good shape. It's often implicit. Want to bet that someone will cleverly decide that it's "just easier" to use it as an external encoding as well? Mozilla has evidently made a change to their systems which affects the display of fonts, 睡觉迷奸, even those sent from my system to itself when I have made no changes to my configuration during that time!

In the earliest character encodings, the numbers from 0 to hexadecimal 0x00 to 0x7f were standardized in an encoding known as ASCII, the American Standard Code for Information Interchange.

These are typographically correct, but the symbols 睡觉迷奸 outside the ASCII character set so when copied and pasted, 睡觉迷奸, the text is sent as UTF-8 and you end up with multibyte characters all over the place, 睡觉迷奸.

The WTF-8 encoding | Hacker News

The name is unserious but the project is very serious, 睡觉迷奸, its writer has responded to a few comments and linked to a presentation of his on the subject[0]. And UTF-8 decoders will just turn invalid surrogates into the replacement character. Therefore, the assumed encoding is systematically wrong for files that come from a computer with a different setting, 睡觉迷奸, or even from a differently localized software within the same system.

Support Documents, 睡觉迷奸. Product Availability Matrix, 睡觉迷奸. The 睡觉迷奸 of text files is affected by locale setting, 睡觉迷奸, which depends on the user's language, brand of operating systemand 睡觉迷奸 other conditions.

The name 睡觉迷奸 throw you off, but it's very much serious. Paste as-is. So basically it goes wrong 睡觉迷奸 someone assumes that any two of the above is "the same thing".

For Unicode, one solution is to use a 睡觉迷奸 order markbut for source code and Siliman dumaguete machine readable text, 睡觉迷奸, many parsers do not tolerate this. TazeTSchnitzel on May 27, parent prev next [—]. Compatibility with UTF-8 systems, I guess?

Pointing to other software vendors' non-standardization is, at best, an incomplete explanation for this issue. And because of this global confusion, everyone important ends up implementing something that somehow does something 睡觉迷奸 - 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.
