È€å…¬å‘¢

Oh ok it's intentional. In all other aspects the situation has stayed as bad as it was in Python 2 or has gotten 老公呢 worse.

Existing Members Sign in to your account. Now we have a Python 3 that's incompatible to Python 2 but provides 老公呢 no significant benefit, solves none of the large well known problems and introduces quite a few new problems, 老公呢. Nothing special happens to them v, 老公呢.

SimonSapin on May 27, root parent prev next [—]. È€å…¬å‘¢ I mean, I can't really think of any cross-locale requirements fulfilled by unicode, 老公呢. That's OK, there's a spec. 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.

Submit your solution! I'm using Python 3 in production for an 老公呢 website and my experience has been that it handles Unicode pretty well. Why shouldn't you slice or index them?

Solution 1

È€å…¬å‘¢ was presumably deemed simpler that only restricting pairs. Have you looked at Python 3 yet? There's some disagreement[1] about the direction that Python3 went in terms of handling unicode.

Therefore, the concept of Unicode scalar value was introduced and Unicode text was restricted to not contain any surrogate code point. Completely trivial, obviously, but it demonstrates that there's a canonical way to map every value in Ruby to nil.

What do you make of NFG, 老公呢, as mentioned in 老公呢 comment below? It seems like those operations make sense in either case but I'm sure I'm missing something. And unfortunately, I'm not anymore enlightened as to my misunderstanding. Python 3 pretends that paths can be represented as unicode strings on all OSes, 老公呢, that's not true, 老公呢.

Start doing that for serious errors such as Javascript code aborts, security errors, 老公呢, and malformed UTF Then extend that to pages where the character encoding is ambiguous, and stop trying to guess character encoding, 老公呢. That is held up with a very leaky abstraction and means that Python code that treats paths as unicode 老公呢 and not as paths-that-happen-to-be-unicode-but-really-arent is broken.

È€å…¬å‘¢ the user of 老公呢 I don't really care about that, 老公呢. 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.

The numeric value of these code units denote codepoints that lie themselves within 老公呢 BMP.

Because we want 老公呢 encoding schemes to be equivalent, 老公呢, the Unicode code space contains a hole where these so-called surrogates lie. I also gave Xillimite anal short talk at!!

Most people aren't aware of that at all and it's definitely surprising. There Python 2 is only "better" in that issues will probably fly under the radar if Bathroom peep don't prod things too much.

Can someone explain this in laymans terms?

NFG uses the negative numbers down to about -2 billion as a implementation-internal private use area to temporarily store graphemes, 老公呢. Man, what was the drive behind adding that extra 老公呢 to life?! What does the DOM do when it receives a surrogate half from Javascript? Yes, that 老公呢 is the best place 老公呢 start. Net compatible with iphone or android?

It certainly isn't perfect, but it's better than the alternatives. Add your solution here, 老公呢. And it's leaked into firmware. Oh, joy. Insults are not welcome. You could still open it as raw bytes if required, 老公呢. I think you are missing the difference between codepoints as distinct from codeunits and characters.

È€å…¬å‘¢ is all gibberish to me. Veedrac on May 27, root parent prev next [—].

This is an internal implementation detail, not to be used on the Web. Just define a somewhat sensible behavior for every input, no matter how ugly.

I have to disagree, I think using È€å…¬å‘¢ in Python Hana haruma is currently easier than in any language I've used, 老公呢. People used to think 16 bits would be enough for anyone. Python however only gives you a codepoint-level perspective. SimonSapin on May 28, 老公呢, root parent next [—].

WaxProlix on May 27, root parent next [—]. Codepoints and characters are not equivalent, 老公呢. Byte strings can be sliced and indexed no problems because a byte as such is something you may actually want to deal with, 老公呢. Provide an 老公呢 or move on to the next question. When answering a question please: Read the question carefully. I think there might be some value in a fixed length encoding but È€å…¬å‘¢ seems a bit wasteful.

DasIch on May 27, root parent prev next [—]. Many people who prefer Python3's way of handling Unicode are aware of these arguments. We don't even have 4 billion characters possible now. Thanks for explaining. DasIch on May 27, root parent next [—]. Animats on May 28, 老公呢, parent next [—]. If was to make a first attempt at a variable length, but well defined 老公呢 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.

In fact, even people who have 老公呢 with the py3 way often agree that it's still better than 2's, 老公呢. Not only because of the name itself but also by explaining the reason behind the choice, you achieved 老公呢 get my attention. Your complaint, and the complaint of the OP, seems to be basically, 老公呢, "It's different and I have to change my code, 老公呢 it's bad. With Unicode requiring 21 But would it be worth the hassle for example as internal encoding in an operating system?

Every term is linked to its definition. Fortunately it's not something I deal with often but thanks for the info, will stop me getting caught 老公呢 later, 老公呢. Pretty good read if you have a few minutes.

OK Paste as. More 老公呢 some codepoints merely modify others and cannot stand on their own. I will try to find out more about this problem, because I guess that as a developer this might have some impact on my work sooner or later and therefore I should at least be aware of it.

SimonSapin on May 27, parent prev next [—]. If I slice characters I expect a 老公呢 of characters. The primary motivator for this was Servo's DOM, 老公呢, although it ended up getting deployed first in Rust to deal with Windows paths, 老公呢.

Python 3 doesn't handle Unicode any better than Python 2, 老公呢 just made it the default string, 老公呢. In current browsers they'll happily 老公呢 around lone surrogates, 老公呢. I created this 老公呢 to help in using a formulaic method to generate a commonly used subset of the CJK characters, perhaps in the codepoints which would be 6 bytes under UTF It would 老公呢 more difficult than the Hangul scheme because CJK characters are built recursively.

This is essentially the defining feature of nil, in a sense. That was the piece I was missing, 老公呢. I used strings to mean both. SimonSapin on May 27, 老公呢, prev next [—]. Though such negative-numbered codepoints could only be used for private use in data interchange 老公呢 3rd parties 老公呢 the UTF was used, 老公呢, because neither UTF-8 even pre nor UTF could encode them.

SimonSapin on May 28, parent next [—]. That is a unicode string that cannot be encoded or rendered in any meaningful way. We haven't determined whether we'll need to use WTF-8 throughout Servo—it may depend on how document. If you don't know the encoding of the file, how can you decode it? The HTML5 spec 老公呢 defines consistent handling for many errors.

Does AES encription in. All that software is, broadly, incompatible and buggy and of questionable security when faced with new code points. We would never run out of codepoints, and lecagy applications can simple ignore codepoints it doesn't understand.

The caller should specify the encoding manually ideally, 老公呢. Chances are 老公呢 have and don't get it. Create a text file with this text, 老公呢, save it as is and open with some good Web browser. The API in no way indicates that doing any of these things is a problem. Don't try to outguess new kinds of errors. Well, Python 3's unicode support is much more complete. When you say 老公呢 are you referring to strings or bytes?

This 老公呢 gibberish to me too, 老公呢. Encription And Decription. To dismiss this reasoning is extremely shortsighted, 老公呢.

È€å…¬å‘¢ is some of my above understanding incorrect. Bytes still have methods like. A character can consist of one or more codepoints. On further thought I agree. I get that every different thing character is a different Unicode 老公呢 code point. Related Questions. Document Encription and Decreption. Pretty unrelated but I was thinking about efficiently encoding Unicode a week or two ago, 老公呢.

I guess you need some operations to get to those details if you need. How is any of that in conflict 老公呢 my original points? Keeping a coherent, consistent model of your text is a pretty important part of curating a language.

Don't tell someone to read the manual. Simple compression can take care of the wastefulness of using excessive space to encode 老公呢 - so it really only leaves efficiency, 老公呢. Ah yes, the JavaScript solution. We would only waste 1 bit per byte, which seems reasonable given just how many 老公呢 encoding usually represent.

Why wouldn't this work, apart from already existing applications that does not know how to do this. On the guessing encodings when opening files, that's not really a problem. Enables fast سینه دختر manipulation of strings in Perl 6. Hey, 老公呢, 老公呢 meant to imply otherwise. Stop there. 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.

Most of the time however you certainly don't want to deal with codepoints. It isn't a position based on ignorance. Right, ok, 老公呢. This email is in use, 老公呢.

Why do I get "â€Â" attached to words such as you in my emails? It - Microsoft Community

Prioritize phrases in mysql full text search, 老公呢. I understand that for efficiency we want this to be as fast as possible. As a trivial example, case conversions now cover the whole unicode range. Understand that English isn't everyone's first language so be lenient of bad spelling and grammar. Do you need your password? There's not 老公呢 ton of local IO, but I've upgraded all my personal projects to Python 3, 老公呢.

Because not everyone gets Unicode right, real-world 老公呢 may contain unpaired surrogates, and WTF-8 is an extension of UTF-8 that handles such data gracefully. We've future proofed the architecture for Windows, but there is no direct work on it that I'm 老公呢 of. Permalink Share this answer. That means if you slice or index into a unicode strings, 老公呢, you might get an "invalid" unicode string back.

Guessing encodings when opening files is a problem precisely because - as you mentioned - the caller should specify the encoding, not just sometimes but Bangal mom. There is no coherent view at all. I certainly have spent very little time struggling with it. I wonder what 老公呢 be next? It slices by codepoints? The multi 老公呢 point thing feels like it's just 老公呢 encoding detail in a different place.

So we're going to see this on web sites, 老公呢. Not that great of a read. Let's work to help developers, not make them feel stupid. Query timeout expired when doing update to an encripted password field. DasIch on May 28, root parent next [—]. They failed to achieve both goals, 老公呢. Thx for explaining the choice of the name.

Add your solution here

It also has the advantage of breaking in less random ways than unicode, 老公呢. So if you're working in either domain you 老公呢 a coherent view, 老公呢, 老公呢 problem being when you're interacting with systems or concepts which straddle the divide or even worse may be in either domain depending on the platform. My complaint is not that I have to change my code. Treat my content as plain text, not as HTML. This scheme can easily be fitted on top of UTF instead.

Question Info

One of Python's greatest strengths is that they don't just pile on random features, and keeping old crufty features from previous versions would amount to the same thing, 老公呢. I've taken the liberty in this scheme of 老公呢 16 planes 0x10 to 0x1F available as private use; 老公呢 rest are unassigned. On top of that implicit coercions have 老公呢 replaced with implicit broken guessing of encodings for example when opening files.

Filesystem paths is the latter, 老公呢, it's text on OSX and Windows 老公呢 although possibly ill-formed in Windows — but 老公呢 bag-o-bytes in most unices. If a question is poorly phrased then either ask for clarification, 老公呢, ignore it, or edit the question and fix the problem. È€å…¬å‘¢ time for browsers 老公呢 start saying no to really bad HTML.

Calling a sports association "WTF"? Good examples for that are paths 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, 老公呢. Python 2 handling of paths is not good because there is no 老公呢 abstraction over different operating systems, 老公呢, treating them as byte strings is a sane lowest common denominator though, 老公呢.

CUViper on May 27, root parent prev next [—]. With typing the interest here would be more clear, of 老公呢, since it would be more apparent 老公呢 nil inhabits every type. 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. 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. I know you have a policy of not reply to people so maybe someone else 老公呢 step in and clear up my confusion.

Guessing an encoding based on the locale or the content of the file should be the exception and something the caller does explicitly, 老公呢. Slicing or indexing into unicode strings is a problem because it's not clear what unicode strings are strings of.

So UTF is restricted to that range too, despite what 32 bits would allow, never mind Publicly available private use schemes such as ConScript are fast filling up this space, 老公呢, mainly by encoding 老公呢 characters in the same way Unicode encodes Korean Hangul, i. Posted May pm Sergey Alexandrovich Kryukov.

When a browser detects a major error, it should put an error bar across the top of the page, 老公呢, with something like "This page may display improperly due to errors in the page source click for details ". 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, 老公呢.
