Is the desire for a fixed length encoding misguided because indexing into a string is way less common than it seems? 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. It's rare enough to not be a top priority.
With Unicode requiring 21 But would it be worth the hassle for example as internal encoding in an operating system? Serious question -- is this a serious project or a joke?
Can anyone tell me what I'm doing wrong here? If was to make Layton benson first attempt at سكس ضوري ايراني variable length, ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’”, but well defined backwards compatible encoding scheme, I would use something like the number of bits upto and including the first 0 bit ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’” defining the number of bytes used for this character.
Dylan on May 27, root parent next [—]. Every term is linked to its definition. There's no good use case. Pointing to other software vendors' non-standardization is, at best, an incomplete explanation for this issue. You signed in with another tab or window. The nature of unicode is that there's always a problem you didn't but should know existed. 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, ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’”.
Mozilla has evidently made ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’” change to their systems which affects the display of fonts, even those sent from my system to itself when I have made no changes to my configuration during that time! 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, ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’”.
Veedrac on May 27, root parent prev ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’” [—]. Compatibility with UTF-8 systems, I guess? We would only waste 1 bit per byte, which seems reasonable given just how many problems encoding usually represent. On further thought I agree. However, I do not think it has solved the problem. An obvious example would be treating UTF as a fixed-width encoding, which is bad because you might end up cutting grapheme clusters in half, and you can easily Jaisn about normalization if you think about it that way.
I guess you need some operations to get to those details if you need. TazeTSchnitzel on May 27, prev next [—], ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’”.

This was presumably deemed simpler that only restricting pairs. This kind of cat always gets out of the bag eventually. It might be removed for non-notability. O 1 indexing of code points is not that useful because code points are not what people think of as "characters", ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’”.
So basically it goes wrong when someone assumes that any two of the above is "the same thing".
Why this over, say, CESU-8? People used to think 16 bits would be enough for anyone. 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]. You switched accounts on another tab or window. Yes, "fixed ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’” is misguided.
This is all gibberish to me. Coding for variable-width takes more effort, but it gives you a better result. I understand that for efficiency we want this to be as fast as possible. Instantly share code, notes, and snippets. Unfortunately, I have been unable to find a way to convert the Chinese document into actual Chinese characters. Simple compression can take care of the ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’” of using excessive space to encode text - so it really only leaves efficiency.
Reload to refresh your session. Because not everyone gets Unicode right, real-world data may contain unpaired surrogates, and WTF-8 is an extension of UTF-8 that handles such data gracefully. The numeric value of these code units denote codepoints that lie themselves within the BMP.
Because we want our encoding schemes to be equivalent, the Unicode code space contains a hole where these so-called surrogates lie. Why wouldn't this work, apart from already existing applications that does not know how to do this. 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.
Then, ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’”, it's possible to make mistakes when converting between representations, eg getting endianness wrong. But inserting a codepoint with your approach would require all downstream bits to be shifted within and across bytes, something that would be a much bigger computational burden, ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’”.

It's often implicit, ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’”.

An interesting possible application for this is JSON parsers.
Dylan on May 27, parent prev next [—]. You signed out in another tab or window. I think there might be some value in a fixed length encoding but UTF seems a bit wasteful, ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’”.
This was gibberish to me too. Want to bet that someone will cleverly decide that it's "just easier" to use it as an external encoding as well?

That's certainly one important source of errors. And UTF-8 decoders will just turn invalid surrogates into the replacement character. Can someone explain this in laymans terms?

We would never run out of codepoints, ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’”, and lecagy applications can simple ignore codepoints it doesn't understand.

It also has the advantage of breaking in less random ways than unicode. Some issues are more subtle: In principle, the decision what should be considered a ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’” character may depend on the language, nevermind the debate about Han unification - but as far as I'm concerned, that's ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’” WONTFIX.
Ah yes, the JavaScript solution. The name might throw you off, but it's very much serious. Well, Python 3's unicode support is much more complete.
That is, you can jump to the middle of a stream and find the next code point by looking at no more than 4 bytes. Pretty unrelated but I was thinking about efficiently encoding Unicode مزز week or two ago. SimonSapin on May 28, parent next [—]. Man, ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’”, what was the drive behind adding that extra complexity to life?!
Having to interact with those systems from a UTF8-encoded world is an issue because they don't guarantee well-formed UTF, ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’”, they might contain unpaired surrogates which can't be decoded to a codepoint allowed in UTF-8 or UTF neither allows unpaired surrogates, for obvious reasons.
Therefore, the concept of Unicode scalar value was introduced and Unicode text was restricted to not contain any surrogate code point. Thor Leach Hello, could you please share your document if that is not confidential to us? See combining code points. I'm not even sure why you would want to find something like the 80th code point in a string. WTF8 exists solely as an internal encoding in-memory representationbut it's very useful there.
This is a recent issue that has cropped up during Mozilla's apparent frantic efforts to ð‘©ð’ð’ð’ƒð’” ð’‘ð’“ð’†ð’”ð’” ð’Šð’ ð’ƒð’–ð’” those version numbers to triple digits before for no clear and valuable reason.
And I mean, I can't really think of any cross-locale requirements fulfilled by unicode. Thanks for explaining.
