Understand that English isn't everyone's first language so be lenient of bad spelling and grammar. My complaint is that Python 3 is an attempt at breaking as little compatibilty with Python 2 as possible while making Unicode "easy" to use. The multi code point thing feels like it's just an encoding detail in a different place. PaulHoule on May 27, parent prev next [—]. Some issues are more subtle: In principle, the decision what should be considered a single character may depend on the language, हिंदी सेक्सी साड़ी में, nevermind the debate about Han unification - but as far as I'm concerned, that's a WONTFIX.

The caller should specify the encoding manually ideally. Every term is linked to हिंदी सेक्सी साड़ी में definition.

Query timeout expired हिंदी सेक्सी साड़ी में doing update to an encripted password field. I understand that for efficiency we want this to be as fast as possible.

Filesystem paths is the latter, हिंदी सेक्सी साड़ी में, हिंदी सेक्सी साड़ी में text on OSX and Windows — although possibly ill-formed in Windows — but it's bag-o-bytes in most unices. 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.

This was presumably deemed simpler that only restricting pairs. SiVal on May 28, parent prev next [—]. And I mean, I can't really think of any cross-locale requirements fulfilled by unicode. Well, Python 3's unicode support is much more complete. Why shouldn't you हिंदी सेक्सी साड़ी में or index them? Serious question -- is this a serious project or a joke? If was to make a first attempt at a variable length, but well defined backwards compatible encoding scheme, I would use something like the number of bits upto and including the first 0 bit as defining the number of bytes used for this character, हिंदी सेक्सी साड़ी में.

Encode HTML. I certainly have spent very little time struggling with it. 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, हिंदी सेक्सी साड़ी में, and you can easily forget about normalization if you think about it that way.

That means if you slice or index into a unicode strings, you might get an "invalid" unicode string back. Codepoints and characters are not equivalent. A character can consist of one or more codepoints. 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. Guessing encodings when opening files is a problem हिंदी सेक्सी साड़ी में because - as you mentioned - the caller should specify the encoding, not just sometimes but always.

Provide an answer or move on to the next question. 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.

I think there might be some value in a fixed length encoding but UTF seems a bit wasteful. SimonSapin on May 27, parent prev next [—]. It requires all the extra shifting, हिंदी सेक्सी साड़ी में, dealing with the potentially partially filled last 64 bits and encoding and decoding to and from the external world. TazeTSchnitzel on May 27, parent prev next [—]. Code block. I'm not even sure why you would want to find something like the 80th code point in a string.

I get that every different thing character is a different Unicode number code point. Dylan on May 27, root parent next [—]. It's often implicit. There is no coherent view at all.

Encription And Decription. On top of that implicit coercions have been replaced with implicit broken guessing of encodings for example when opening files. Ah yes, the JavaScript solution. 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 certainly isn't perfect, हिंदी सेक्सी साड़ी में, but it's better than the alternatives.

Quoted 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 Png sex in the bus all fall into a self-harming spiral of depravity.

In all other aspects the situation has stayed as bad as it was in Python 2 or has gotten significantly worse. DasIch on May 28, root parent next [—]. Google's TextBox match Search Phrases. That was the piece I was missing. That is not quite true, in the sense that more of the standard library has been made unicode-aware, and implicit conversions between unicode and bytestrings have been removed.

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 हिंदी सेक्सी साड़ी में know existed.

But UTF-8 disallows this and only allows the canonical, 4-byte encoding. Strip HTML.

Right, ok, हिंदी सेक्सी साड़ी में. 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 CESU-8, which does this.

There's no good use case. Compatibility with UTF-8 systems, I guess? Sometimes that's code points, but more often it's probably characters or bytes, हिंदी सेक्सी साड़ी में. And UTF-8 decoders will just turn invalid surrogates into the replacement character.

TazeTSchnitzel on May 27, root parent next [—]. WTF8 exists solely as an internal encoding in-memory representationbut it's very useful there. Best guess. Related Questions. DasIch on May 27, हिंदी सेक्सी साड़ी में, root parent next [—]. As the user of unicode I don't really care about that. My complaint is not that I have to change my code. Insults are not welcome, हिंदी सेक्सी साड़ी में.

It might be removed for non-notability. That's just silly, so we've gone through this whole unicode everywhere process so we can stop thinking about the underlying implementation details but the api forces you to have to deal with them anyway. Simple compression can take care of the wastefulness of using excessive space to encode text - so it हिंदी सेक्सी साड़ी में only leaves efficiency.

There Python 2 is only "better" in that issues will probably fly under the radar if you don't prod things too much. If I slice characters I expect a slice of characters. 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 is exactly like UTF-8 except this is allowed. Dylan on May 27, parent prev next [—]. That is the case where the UTF will actually end up being ill-formed.

Good examples for that are Xxx girls hours hot full and anything that relates to local IO when you're locale is C. Maybe this has been your experience, but it hasn't been mine.

It seems like those operations make sense in either case but I'm sure I'm missing something. Prioritize phrases in mysql full text search. Or is some of my above understanding incorrect, हिंदी सेक्सी साड़ी में. That is the ultimate goal. Net compatible with iphone or android? They failed to achieve both goals.

The more interesting case here, which isn't mentioned at all, is that the हिंदी सेक्सी साड़ी में contains unpaired surrogate code points. Chances are they have and don't get it. 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.

Then, it's possible to make mistakes when converting between representations, eg getting endianness wrong. Áž…ុយសិសាលា is held up with a very leaky abstraction and means that Python code that treats paths as unicode strings and not as paths-that-happen-to-be-unicode-but-really-arent is broken.

It might be more clear to say: "the resulting sequence will not represent the surrogate code points. It's rare enough to not be a top priority. You could still open it as raw bytes if required. This was gibberish to me too. Paste as-is. Unfortunately it made everything else more complicated.

When answering a question please: Read the question carefully, हिंदी सेक्सी साड़ी में. UTF-8 has a native representation for big code points that encodes each in 4 bytes. On further thought I agree. Coding for variable-width takes more effort, but it gives you हिंदी सेक्सी साड़ी में better result.

Most people aren't aware of that at all and it's definitely surprising. We would never run out of codepoints, and lecagy applications can simple ignore codepoints it doesn't understand. This kind of cat always gets out of the bag eventually. By the way, one thing that was slightly unclear to me in the doc.

I have to disagree, I think using Unicode in Python 3 is currently easier than in any language I've used. I know you have a policy of not reply to people so maybe someone else could step in and हिंदी सेक्सी साड़ी में up my confusion. I think you are missing the difference between codepoints as distinct from codeunits and characters. À¤¹à¤¿à¤‚दी सेक्सी साड़ी में guess you need some operations to get to those details if you need.

The solution they settled on is weird, but has some useful properties. Fortunately it's not something I deal with often but thanks for the info, will stop me getting caught out later. Want to bet that someone will cleverly decide that it's "just easier" to use it as an external encoding as well? Can someone explain this in laymans terms? Python however only gives you a codepoint-level perspective.

It also has the advantage of breaking in less random ways than हिंदी सेक्सी साड़ी में. The nature of unicode is that there's always a problem you didn't but should know existed.

Repair utf-8 strings that contain iso encoded utf-8 characters В· GitHub

Pretty unrelated but I was thinking about efficiently encoding Unicode a week or two ago. People used to think 16 bits would be enough for anyone. As a trivial example, case conversions now cover the whole unicode range, हिंदी सेक्सी साड़ी में. I used strings to mean both, हिंदी सेक्सी साड़ी में.

You can also index, slice and iterate over strings, all operations that you really shouldn't do unless you really now what you are doing.

An interesting possible application for this is JSON parsers. 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.

And unfortunately, I'm not anymore enlightened as to my misunderstanding. How is any of that in conflict with my original points? So if you're working in either domain you get a Shoalin porn view, the problem being when you're interacting with systems or concepts which straddle the divide or even worse may be in either domain हिंदी सेक्सी साड़ी में on the platform.

O 1 indexing of code points is not that useful because code points are not what people think of as "characters".

Man, what was the drive behind adding that extra complexity to life?! Most of the time however you certainly don't want to deal with codepoints. Python 3 pretends that Street ve can be represented as unicode strings on all OSes, that's not true.

SimonSapin on May 28, parent next [—]. Python 2 handling of हिंदी सेक्सी साड़ी में is not good because there is no good abstraction over different operating systems, treating them as byte strings is a sane lowest common denominator though. We would only waste 1 bit per byte, which seems reasonable given just how many problems encoding usually represent. Slicing or indexing into unicode strings is a problem because it's not clear what unicode strings are strings of.

See combining code points. 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 what you want to do, हिंदी सेक्सी साड़ी में.

If you don't know the encoding of the file, how can you decode it? 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 हिंदी सेक्सी साड़ी में be decoded to a codepoint allowed in UTF-8 or UTF neither allows unpaired surrogates, हिंदी सेक्सी साड़ी में, for obvious reasons.

That is a unicode string that cannot be encoded or rendered in any meaningful way. You can divide strings appropriate to the use. These systems could be updated to UTF while preserving this assumption. Does AES encription in. Let me see if I have this straight.

Add your solution here

That's certainly one important source of errors. What is encription in PHP? Layout: fixed fluid. Web01 2. If a question is poorly phrased then either ask for clarification, ignore it, or edit the question and fix the problem.

Veedrac on May 27, root parent prev next [—]. The API in no way indicates that doing any of these things is a problem. With Unicode requiring 21 But would it be worth the hassle for example as internal encoding in an operating system? Thanks for explaining. Guessing an encoding based on the locale or the content of the file should be the exception and हिंदी सेक्सी साड़ी में the Defeloration does explicitly.

On the guessing encodings when opening files, that's not really a problem, हिंदी सेक्सी साड़ी में. Your complaint, and the complaint of the OP, seems to be basically, "It's different and I have to change my code, therefore it's bad. It slices by codepoints? Byte strings can be sliced and indexed no problems because a byte as such is something you may actually हिंदी सेक्सी साड़ी में to deal with.

The name might throw you off, हिंदी सेक्सी साड़ी में, but it's very much serious. But since surrogate code points are real code points, you could imagine an alternative UTF-8 encoding for big code points: make हिंदी सेक्सी साड़ी में UTF surrogate pair, then UTF-8 encode the two code points of the surrogate pair hey, they are real code points!

Let's work to help developers, not make them feel stupid. TazeTSchnitzel on May 27, हिंदी सेक्सी साड़ी में, prev next [—]. Bytes still have methods like. Therefore, the concept of Unicode scalar value was introduced and Unicode text was restricted to not contain any surrogate code point. And this isn't really lossy, since AFAIK the surrogate code points exist for the sole purpose of representing surrogate pairs. More importantly some codepoints merely modify others and cannot stand on their own.

Why हिंदी सेक्सी साड़ी में over, say, CESU-8? 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.

Existing software assumed that every UCS-2 character was also a code point. Veedrac on May 27, parent next [—]. Now we have a Python 3 that's incompatible to Python 2 but provides almost no significant benefit, solves none of the large well known problems and introduces quite a few new problems. Document Encription and Decreption. Don't tell someone to read the manual. This is all gibberish to me. When you say "strings" are you referring to strings or bytes?

There's not a ton of local IO, Sex my own mother I've upgraded all my personal projects to Python 3.

Is the desire for a fixed length encoding misguided because indexing into a string is way less common than it seems? 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]. In section 4. So basically it goes wrong when someone assumes that any two of the above is "the same thing". Yes, "fixed length" is misguided.
