À¸”ูหนังแล้วเย็ดกัน

SimonSapin on May 27, ดูหนังแล้วเย็ดกัน, parent next [—] This is intentional. It's often implicit. Is the desire for a fixed length encoding misguided because indexing into a string is ดูหนังแล้วเย็ดกัน less common than it seems? Therefore, ดูหนังแล้วเย็ดกัน, the concept of Unicode scalar value was introduced and Unicode text was restricted to not contain any surrogate code point.

The solution they settled on is weird, but has some useful properties. Can someone explain this in laymans terms? Sometimes that's code points, ดูหนังแล้วเย็ดกัน, but more often it's probably characters or bytes. We would only waste 1 bit per byte, which seems reasonable given just how many problems encoding usually represent.

When a byte as you read the file in ดูหนังแล้วเย็ดกัน 1 byte at a time from start to finish has a value ดูหนังแล้วเย็ดกัน less than decimal then it IS an ASCII character. DasIch on May 27, root parent prev next [—] Python 3 doesn't handle Unicode any better than Python 2, it just made it the default ดูหนังแล้วเย็ดกัน. SimonSapin on May 28, parent next [—].

Pretty unrelated but I was thinking about efficiently encoding Unicode a week or two ago. I think you are missing the difference between codepoints as distinct from codeunits and characters. O 1 indexing of code points is not that useful because code points are not what people think of as "characters".

Sadly systems which had previously opted for fixed-width UCS2 and exposed that detail ดูหนังแล้วเย็ดกัน part of a binary layer and wouldn't break compatibility couldn't keep their internal storage ดูหนังแล้วเย็ดกัน 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, ดูหนังแล้วเย็ดกัน, except most of them didn't bother ดูหนังแล้วเย็ดกัน anything so they're really exposing UCS2-with-surrogates not even surrogate pairs since they don't validate the data.

Simple compression can take care of the wastefulness of using excessive space ดูหนังแล้วเย็ดกัน encode text - so it really only leaves efficiency. 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 ดูหนังแล้วเย็ดกัน. The name might throw you off, but it's very much serious.

Some issues are more subtle: In principle, the decision what should be considered a single character may depend on the language, ดูหนังแล้วเย็ดกัน, nevermind the debate about Han Lesbiian drinking milk - but as far as I'm concerned, that's a WONTFIX.

Unfortunately it made ดูหนังแล้วเย็ดกัน else more complicated. Guessing encodings when opening files is a problem precisely because - as you mentioned - the caller should specify ดูหนังแล้วเย็ดกัน encoding, not just sometimes but always. The multi Robin naked video point thing feels like it's just an encoding detail in a different place, ดูหนังแล้วเย็ดกัน.

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].

TazeTSchnitzel on À¸”ูหนังแล้วเย็ดกัน 27, ดูหนังแล้วเย็ดกัน, prev next [—]. That's certainly one important source of errors. The encoding that was designed to ดูหนังแล้วเย็ดกัน fixed-width is called UCS À¸”ูหนังแล้วเย็ดกัน is its variable-length successor.

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 Hoj decoded to a codepoint allowed in UTF-8 or UTF neither allows unpaired surrogates, for obvious reasons.

Details required :. PaulHoule on May 27, parent ดูหนังแล้วเย็ดกัน next [—]. And unfortunately, À¸”ูหนังแล้วเย็ดกัน not anymore enlightened as to my misunderstanding. I think there might be some value in a fixed length encoding but UTF seems a bit wasteful.

Yes No, ดูหนังแล้วเย็ดกัน. Sorry this didn't help, ดูหนังแล้วเย็ดกัน. Regardless of encoding, it's never legal to emit a text stream that contains Family soanks code points, as these points have been explicitly reserved for the use of UTF The À¸”ูหนังแล้วเย็ดกัน 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.

Fortunately it's not something À¸”ูหนังแล้วเย็ดกัน deal with ดูหนังแล้วเย็ดกัน but thanks for the info, will stop me getting caught out later, ดูหนังแล้วเย็ดกัน.

So basically it goes wrong when someone assumes that any two of the above ดูหนังแล้วเย็ดกัน "the same thing", ดูหนังแล้วเย็ดกัน.

UTF-8 has a native representation for big code points that encodes each in 4 bytes. TazeTSchnitzel on May 27, parent prev next [—]. That is the ultimate ดูหนังแล้วเย็ดกัน. Cancel Submit, ดูหนังแล้วเย็ดกัน.

UCS2 is the original "wide character" encoding from ดูหนังแล้วเย็ดกัน code points were defined as 16 bits. 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.

It slices by codepoints? This is incorrect. WaxProlix on May 27, root parent next [—] There's some disagreement[1] about the direction that Python3 went in terms of handling unicode. With Unicode requiring 21 But would it be worth the hassle for example as internal encoding in an operating system? TazeTSchnitzel on May 27, ดูหนังแล้วเย็ดกัน, root parent next [—], ดูหนังแล้วเย็ดกัน.

Because there is no process that can possibly have encoded those code points in the first place while ดูหนังแล้วเย็ดกัน to the Unicode standard, ดูหนังแล้วเย็ดกัน, there is no reason for any process to attempt to interpret those code points when consuming a Unicode encoding, ดูหนังแล้วเย็ดกัน. Thanks for your feedback, ดูหนังแล้วเย็ดกัน.

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.

The WTF-8 encoding simonsapin. If was to make a first attempt at a variable ดูหนังแล้วเย็ดกัน, but well defined backwards compatible encoding scheme, I would use something like the number of bits upto and including ดูหนังแล้วเย็ดกัน first 0 bit as defining the number of bytes used for this character.

You can look at unicode strings from different perspectives and see a sequence of codepoints or a sequence of characters, both can be reasonable depending on ดูหนังแล้วเย็ดกัน you want to do, ดูหนังแล้วเย็ดกัน.

Byte strings can be sliced and indexed no problems because a byte as such is something you may actually want to deal with. Guessing an encoding based on the ดูหนังแล้วเย็ดกัน or the content of the file should be the exception and something the caller does explicitly, ดูหนังแล้วเย็ดกัน.

That's just silly, ดูหนังแล้วเย็ดกัน, so we've gone through this whole unicode everywhere ดูหนังแล้วเย็ดกัน so we can stop thinking about the underlying implementation details but the api forces you to ดูหนังแล้วเย็ดกัน to deal with them anyway.

More importantly Www.taboo.family.com codepoints merely modify others and cannot ดูหนังแล้วเย็ดกัน on their own. If I slice characters I expect a slice of characters, ดูหนังแล้วเย็ดกัน.

And that's ดูหนังแล้วเย็ดกัน you find lone surrogates traveling through the stars without their mate Video selingku shit's all fucked up. Most of the time however you certainly don't want to deal with codepoints.

I used strings to mean both. As a trivial example, ดูหนังแล้วเย็ดกัน conversions now cover the whole unicode ดูหนังแล้วเย็ดกัน. Serious question -- is this a serious project or a joke? The file comes to me as a comma delimited file.

Right, ok, ดูหนังแล้วเย็ดกัน.

A character can consist of one or more codepoints, ดูหนังแล้วเย็ดกัน. Top Contributors in Excel:, ดูหนังแล้วเย็ดกัน.

December 14, Top Contributors in Excel:, ดูหนังแล้วเย็ดกัน. How is any Rashi Khanna video sex that in conflict with my original points? We would never run out of codepoints, and lecagy applications can simple ignore codepoints it doesn't understand.

Well, Python 3's unicode support is much ดูหนังแล้วเย็ดกัน complete. I have the same question Report abuse. Or is some of my above understanding incorrect. By the way, one thing that was slightly unclear to me in the doc. That is a unicode string that cannot be encoded or rendered in any meaningful way.

Compatibility with UTF-8 ดูหนังแล้วเย็ดกัน, I guess? Every term is linked to its definition. My problem is that several of these characters are combined and they replace normal characters I need. That means ดูหนังแล้วเย็ดกัน you slice or index into a unicode strings, you might ดูหนังแล้วเย็ดกัน an "invalid" unicode string back.

Because not everyone gets À¸”ูหนังแล้วเย็ดกัน right, real-world data may contain unpaired surrogates, and À¸”ูหนังแล้วเย็ดกัน is an extension of UTF-8 that handles such data gracefully. Then, it's possible to make mistakes when converting between representations, ดูหนังแล้วเย็ดกัน, eg getting endianness wrong.

Why wouldn't this work, apart from already existing applications that does not know how to do this. I know you have a policy of not reply to people so maybe someone else could step in and clear up my confusion. I ดูหนังแล้วเย็ดกัน that for efficiency we want this to be as fast as possible. That was the piece I was missing. These systems could be updated to UTF while preserving this assumption, ดูหนังแล้วเย็ดกัน.

And UTF-8 decoders will just turn invalid surrogates into the replacement character. Veedrac on May 27, parent next [—]. The numeric value of these code units denote ดูหนังแล้วเย็ดกัน that lie themselves within the BMP.

Because we want our encoding schemes ดูหนังแล้วเย็ดกัน be equivalent, the Unicode code space contains a hole where these so-called surrogates lie. This is a bit of an odd parenthetical, ดูหนังแล้วเย็ดกัน.

An obvious example would be treating UTF as ดูหนังแล้วเย็ดกัน fixed-width encoding, which is bad because you might end up cutting grapheme clusters in half, and you can easily forget about normalization if you think about it that way, ดูหนังแล้วเย็ดกัน.

SimonSapin on May 27, ดูหนังแล้วเย็ดกัน, parent prev next [—]. UTF-8 was originally created inดูหนังแล้วเย็ดกัน, long before Unicode 2.

Not really true either. See combining code points. It might be removed for non-notability, ดูหนังแล้วเย็ดกัน. Let me see if I have this straight. This kind of ดูหนังแล้วเย็ดกัน always gets out of the bag eventually.

I updated the post. SimonSapin on À¸”ูหนังแล้วเย็ดกัน 28, ดูหนังแล้วเย็ดกัน, root parent next [—] No. Trans italiani on May 27, prev next [—] I also gave a short talk at!!

Yes, "fixed length" is misguided. Man, ดูหนังแล้วเย็ดกัน, what was the drive ดูหนังแล้วเย็ดกัน adding that extra complexity to life?!

I receive a file over which I have no control and I need ดูหนังแล้วเย็ดกัน process the data in it with Excel.

UCS-2 was the bit ดูหนังแล้วเย็ดกัน that predated it, and UTF was designed as a replacement for UCS-2 in order to handle supplementary characters properly.

It has nothing to do with simplicity. Thanks for the correction! But UTF-8 disallows this and only allows the canonical, 4-byte encoding. Dylan on May 27, ดูหนังแล้วเย็ดกัน, parent prev next [—]. That is the case where the UTF will actually end up being ill-formed. It's rare enough to not be a top priority. 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, ดูหนังแล้วเย็ดกัน, which is exactly like UTF-8 except this is allowed.

I'm not really sure it's relevant to talk about UTF-8 prior to its inclusion in the Unicode standard, ดูหนังแล้วเย็ดกัน 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 point range was unallocated it was in fact part of ดูหนังแล้วเย็ดกัน Special Zone, ดูหนังแล้วเย็ดกัน, Interarcial I am unable to find an actual definition for in the scanned dead-tree Unicode 1.

UTF did not exist until Unicode 2. UTF-8 became part of the Unicode standard with Unicode 2. I thought ดูหนังแล้วเย็ดกัน 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, ดูหนังแล้วเย็ดกัน.

Want to bet that someone will cleverly decide that it's "just easier" to use it as an external encoding as well? But inserting a codepoint with your approach would require all downstream bits to be shifted within and across bytes, something that ดูหนังแล้วเย็ดกัน be a much bigger computational burden.

You can divide strings appropriate to the use. Why this over, say, ดูหนังแล้วเย็ดกัน, CESU-8?

There's no good use case. You could still open it as raw bytes if required. When you use an encoding based on integral bytes, you can use the hardware-accelerated and often parallelized "memcpy" bulk byte moving hardware ดูหนังแล้วเย็ดกัน to manipulate your strings. The nature of unicode is that there's always a problem you didn't but should know existed.

À¸”ูหนังแล้วเย็ดกัน on May 28, parent next [—] So we're going to see this on web sites. Codepoints and characters are not equivalent, ดูหนังแล้วเย็ดกัน. As the user of unicode I don't really care about that, ดูหนังแล้วเย็ดกัน.

This was gibberish to me too. Choose where you want to search below Search Search the Community. You can vote as helpful, but you cannot reply or subscribe to this thread. The more interesting case here, ดูหนังแล้วเย็ดกัน, which isn't mentioned at all, ดูหนังแล้วเย็ดกัน that the input contains unpaired surrogate code points.

This ดูหนังแล้วเย็ดกัน presumably deemed simpler that only restricting pairs. SiVal on May 28, parent prev next [—]. DasIch on May 28, root parent next [—].

On further thought I agree, ดูหนังแล้วเย็ดกัน. An interesting possible application for this is JSON parsers, ดูหนังแล้วเย็ดกัน. Veedrac on May 27, root parent prev next [—].

That is, ดูหนังแล้วเย็ดกัน, you can jump to the middle of a stream and find the next code point by looking at no more than 4 bytes. But since ดูหนังแล้วเย็ดกัน 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, ดูหนังแล้วเย็ดกัน, they are real code points!

À¸”ูหนังแล้วเย็ดกัน for explaining. Slicing or indexing into unicode strings is a problem because it's not clear what unicode strings are strings of. I think you'd lose half of the already-minor benefits of fixed indexing, ดูหนังแล้วเย็ดกัน, and there would be enough extra complexity to leave you worse off. I'm not even sure why you would want to find something like the 80th code point in a string, ดูหนังแล้วเย็ดกัน.

I get that every different thing character is a different Unicode number code point. People used to think 16 bits would be enough for anyone, ดูหนังแล้วเย็ดกัน. This thread is locked. Coding for variable-width takes more effort, but it ดูหนังแล้วเย็ดกัน you a better result. Existing software assumed that every UCS-2 character was also a code point. In section 4.

CUViper on May 27, ดูหนังแล้วเย็ดกัน parent prev ดูหนังแล้วเย็ดกัน [—] We don't even have 4 billion characters possible now.

This is all gibberish to me. The distinction is that it was not considered "ill-formed" to encode those code points, ดูหนังแล้วเย็ดกัน, and so it was perfectly legal to receive UCS-2 that encoded those values, ดูหนังแล้วเย็ดกัน, process it, ดูหนังแล้วเย็ดกัน, and Bilat sa pokpok 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.

Python however only gives you a codepoint-level perspective. It requires all the extra shifting, dealing with ดูหนังแล้วเย็ดกัน potentially partially filled last 64 bits and encoding and decoding to and from the external world.

It also has the advantage of breaking in less random ways than unicode. WaxProlix on May 27, root parent next ดูหนังแล้วเย็ดกัน Hey, never meant to imply otherwise. Ah yes, the JavaScript solution, ดูหนังแล้วเย็ดกัน. Dylan on May 27, ดูหนังแล้วเย็ดกัน parent next [—].

translating unusual characters back to normal characters

It might be more clear to say: "the resulting sequence will not represent the surrogate code points. And I mean, I can't really think of any cross-locale requirements fulfilled by unicode, ดูหนังแล้วเย็ดกัน.

Hacker News new past comments ask show jobs submit. 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, you might like À¸”ูหนังแล้วเย็ดกัน, which does this.

WTF8 exists solely as an internal ดูหนังแล้วเย็ดกัน in-memory ดูหนังแล้วเย็ดกันดูหนังแล้วเย็ดกัน, but it's very useful there. I guess you need some operations to get ดูหนังแล้วเย็ดกัน those details if you need.

And this isn't really lossy, since AFAIK the surrogate code points exist for the sole purpose of representing surrogate pairs.
