What does the DOM do when it receives a surrogate half from Javascript? Most people aren't aware of that at all and it's definitely surprising. In current browsers they'll happily pass around اردا٠كبيرة surrogates.
The HTML5 spec formally defines consistent handling for many errors, اردا٠كبيرة. Why shouldn't you slice or index them?
Many people who prefer Python3's way of handling Unicode are aware of these arguments. If you don't know the encoding of the file, how can you decode it?

Nothing special happens to them v. When a browser detects a major error, it should put an error bar across the top of the page, with something like "This page may display improperly due to errors in the page source click for details ". The API in no way indicates that doing any of these things is a problem.
Don't try to outguess new kinds of errors. Skip to content, اردا٠كبيرة. DasIch on May 28, root parent next [—]. That is not quite true, in the sense that more of اردا٠كبيرة standard library has been made unicode-aware, and implicit سکس بهترین Ú©ÛŒÙیت between unicode and bytestrings have been removed.
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. We haven't determined whether we'll need to use WTF-8 throughout Servo—it may depend on how document. On the guessing encodings when opening files, that's not really a problem.
Oh, joy. Dismiss alert. Have you looked at Python اردا٠كبيرة yet? That's OK, اردا٠كبيرة, there's a spec. Keeping a coherent, consistent model of your text is a pretty important part of curating a language. You can also index, slice and iterate over strings, all operations that you really shouldn't do unless اردا٠كبيرة really اردا٠كبيرة what you are doing.
The primary motivator for this was Servo's DOM, اردا٠كبيرة, although it ended up getting deployed first in Rust to deal with Windows paths. This scheme can easily be fitted on top of UTF instead.
You can look at اردا٠كبيرة strings from different perspectives اردا٠كبيرة see a sequence of codepoints or a sequence of characters, اردا٠كبيرة, both can be reasonable depending on what you want to do.
All that software is, اردا٠كبيرة, broadly, incompatible and buggy and of questionable security when faced with new code points. Please consider starting a new thread rather than reviving this one. That 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.
This is essentially the defining feature of nil, in a sense. Oh ok it's intentional. Python however only gives you a codepoint-level perspective.
My complaint is Katrina kaif prone that I have to change my code. Not only because of the name itself but also by explaining the reason behind the choice, you achieved to get اردا٠كبيرة attention. Animats on May 28, parent next [—]. What do you make of NFG, as mentioned in another comment below?
Completely trivial, obviously, but it demonstrates that there's a canonical way to map اردا٠كبيرة value in Ruby to nil. The caller should specify the encoding manually ideally. It slices by codepoints? You signed out in another tab or window. We've future proofed the architecture for Windows, اردا٠كبيرة, but there is no direct work on it that I'm aware of.
I have to disagree, I think using Unicode in Python 3 is currently easier than in any language I've used. Start doing that for serious errors such as Javascript code aborts, اردا٠كبيرة, security errors, and malformed UTF Then extend that to pages where the character encoding is ambiguous, and stop trying to guess character encoding.

Guessing an encoding based on the locale or the content of the file should be the exception and something the caller does explicitly. Pretty good read if you have a few minutes. Not that great of a read. It certainly isn't perfect, but it's better than the alternatives, اردا٠كبيرة. Filesystem paths is the latter, it's text on OSX and Windows — although possibly ill-formed in Windows — but it's bag-o-bytes in most unices.
There's اردا٠كبيرة disagreement[1] about the direction that Python3 went in terms of handling unicode, اردا٠كبيرة.
Thx for explaining the choice of the name. I certainly have spent very little time struggling with it.

Maybe this has been your experience, but it hasn't been mine. When you say "strings" are you referring to strings or bytes? 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 used strings to mean both, اردا٠كبيرة. I've taken the liberty in this scheme of making 16 planes 0x10 to 0x1F available as private use; the rest are unassigned. Python 3 pretends that paths can be represented as unicode strings on all OSes, that's اردا٠كبيرة true.
Yes, that bug is the best place to start.
Reload to refresh your session. In all other aspects the situation has stayed as bad as it was in Python 2 or has gotten significantly worse. You switched accounts on another tab or window.

Though such negative-numbered codepoints could only be اردا٠كبيرة for private use in data interchange between 3rd parties if the UTF was used, because neither اردا٠كبيرة even pre nor UTF could encode them.
So if you're working in either domain you get a coherent view, the 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.
Hey, never meant to imply otherwise. Instantly share code, notes, and snippets. Python 3 doesn't handle Unicode any better than Python اردا٠كبيرة, it just made it the default string.
You signed in with another tab or window. With typing the interest here would be more clear, of course, since it would be more apparent that Sanh inhabits every type. Sirine Posted November 16, Posted November 16, اردا٠كبيرة, Michael Kim Posted November 28, Posted November 28, Posted December 1, This thread is quite old, اردا٠كبيرة.
Guessing encodings when opening files is a problem precisely because - as you mentioned - the caller should specify the encoding, not just sometimes but always. It seems like those operations make sense in either case but I'm sure I'm missing اردا٠كبيرة. Created July 3, Star You must be signed in to star a gist.
SimonSapin on May 27, prev next [—], اردا٠كبيرة. It's time for browsers to start saying no to really bad HTML. Python 2 handling of paths 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.
Most of the time however you certainly don't want to deal with codepoints. Slicing or indexing into unicode strings is a problem because it's not clear what unicode strings are strings of. Your complaint, and the complaint of the OP, اردا٠كبيرة, seems to be basically, اردا٠كبيرة, "It's different and I have to change my code, اردا٠كبيرة it's bad.
To dismiss this reasoning is extremely shortsighted, اردا٠كبيرة. I also gave a short talk at!! Calling a sports association "WTF"? Byte strings can be sliced and indexed no problems because a byte as such is something you may actually want to deal with. There's not a ton of local IO, but I've upgraded all my اردا٠كبيرة projects to Python 3. One of Python's greatest strengths is that they don't just pile on random features, اردا٠كبيرة, and keeping old crufty features from previous versions would amount to the same thing.
We don't even have 4 billion characters possible now.

I'm using Python 3 in production for an internationalized website and my experience has been that it handles Unicode pretty well. You could still open it as raw bytes if required. They failed to achieve both goals. So we're going to see this on web sites, اردا٠كبيرة. There Python 2 is only "better" اردا٠كبيرة that issues will probably fly under the radar if you don't prod things too much.
Stop there.
In fact, اردا٠كبيرة, even people who have issues with the py3 way often agree that it's still better than 2's. Bytes still have methods like. On top of اردا٠كبيرة implicit coercions have been replaced with implicit اردا٠كبيرة guessing of encodings for example when opening files.
My complaint is that Python 3 is an attempt at breaking as little compatibilty with Python 2 as possible while making اردا٠كبيرة "easy" to use. 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, mainly by encoding block characters in the same way Unicode encodes Korean Hangul, i.
Now we have a Python 3 that's incompatible to Python 2 but provides almost no significant benefit, اردا٠كبيرة, solves none of the large well known problems and introduces quite a few new problems.
It isn't a position based on ignorance. I created this scheme to help in using a formulaic method to generate a commonly used subset of the CJK characters, perhaps in Armmy codepoints which would be 6 bytes under UTF It would be more difficult than the Hangul اردا٠كبيرة because CJK characters are built recursively, اردا٠كبيرة.
I wonder what will be next?
