Many people who prefer Python3's way of handling Unicode are aware of these arguments. Well, Python 3's unicode support is much more complete. 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.
The caller should specify the encoding manually ideally. I know you have a policy of not reply to people so maybe someone else could step in and clear à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸± my confusion.
Thor Leach. That is held up with a very leaky abstraction and means that Python code that Imglorious paths as unicode strings and not as paths-that-happen-to-be-unicode-but-really-arent is broken, à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸±.

I guess you need some operations to get to those details if you need.
DasIch on May 27, root parent prev next [—]. When you say "strings" are you referring to strings or bytes? It isn't a position based on ignorance. It certainly isn't perfect, but it's better than the alternatives. Guessing encodings when opening files is a problem precisely because - as you mentioned - the caller should specify the à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸±, not just sometimes but always.
I understand that for efficiency we want this to be as à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸± as possible, à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸±.
That was the piece I was missing.
More importantly à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸± codepoints merely modify others and cannot stand on their own. Guessing an encoding based on the locale or the content of the file should be the exception and something the caller does explicitly, à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸±.
Keeping a coherent, consistent model of your text is a pretty important part of curating a language. On further thought I agree.
As the user of unicode I don't really care about that. The multi code point thing feels like it's just an encoding detail in a different place. So if you're working in either domain you get a coherent view, à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸±, the à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸± 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.
There is no coherent view at all, à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸±. Therefore, the concept of Unicode scalar value was introduced and Unicode text was restricted to not contain any surrogate code point.
We would never run out à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸± codepoints, and lecagy applications can simple ignore codepoints it doesn't understand. Every term is linked to its definition.
That means if you slice or index into a unicode strings, you might get an "invalid" unicode string à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸±. Byte strings can be sliced and indexed no problems because a byte as such is something you may à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸± want to deal with. Thanks for explaining.
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. Codepoints and characters are not equivalent. And unfortunately, I'm not anymore enlightened as to my misunderstanding. Fortunately it's not something I deal with Asian bata but thanks for the info, will stop me getting caught out later.

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. I have to disagree, à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸±, I think using À¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸± in Python 3 is currently easier than in any language I've used.

Because we want our encoding schemes to be equivalent, the Unicode code space contains a hole where these so-called surrogates lie.
People used to think Bbwwww bits would be enough for anyone. 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.
There's some disagreement[1] about the direction that Python3 went in terms of handling unicode. SimonSapin on May 27, parent prev next [—].
Can someone explain this in laymans terms? Slicing or indexing into unicode strings is a problem because it's not clear what unicode strings are strings of. They failed to achieve both goals. Have you looked at Python 3 yet?
I used strings to mean à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸±. On the guessing encodings when opening files, that's not really a problem.
In all other aspects the situation has stayed as bad as it was in Python 2 or has gotten significantly worse. And I mean, I can't really think of any cross-locale requirements fulfilled by unicode, à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸±.
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.

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. There Python 2 is only "better" in that issues will probably fly under the radar if you don't prod things too à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸±. I also gave a short talk at!! This was presumably deemed simpler that only restricting pairs.
Python 3 pretends that paths can be represented as unicode strings on all OSes, that's not true. Right, à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸±, ok. Most people aren't aware of that at all and it's definitely surprising. Python 3 doesn't handle Unicode any better than Python 2, it just made it the default string. I get that every different thing character à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸± a different Unicode number code point.

I'm using Python 3 in production for an internationalized website and my experience has been that it handles Unicode pretty well. Pretty good read if you have a few minutes. This is all gibberish to me. 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 à¹à¸à¸šà¹€à¸¢à¹‡à¸”à¸à¸±à¸šà¸Šà¸¹à¹‰à¸•à¸à¸™à¹€à¸¡à¸µà¸¢à¹„ม่à¸à¸¢à¸¹à¹ˆ เมียà¸à¸± the first 0 bit as defining the number of bytes used for this character.
