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, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. Guessing an encoding based on the locale or the content of the file should be the exception and something the caller ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า explicitly.
Can someone explain this in laymans terms? There Python 2 is only "better" in that issues will probably fly under the radar if you don't prod things too much, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า.

You could still open it as raw bytes if required. So if you're working in either domain ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า 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. How is any of that in ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า with my original points?
Keeping a coherent, consistent model of your text is a pretty important part of curating a language. Nothing special happens to them v. Perhaps Art. But that, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า, of course, is a critical realisation.
When Is a "Plain Meaning" Not Plain? - Opinio Juris
Have you looked at Python 3 yet? That is a unicode string that cannot be encoded or ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า in any meaningful way. Therefore, the concept of Unicode scalar value was introduced and Unicode text was restricted to not contain any surrogate code point.
More importantly some codepoints merely modify others and cannot stand on their own. When you say "strings" are you referring to strings or bytes?
If you don't know the encoding of the file, how can you decode it? Here is Art. Because it means that we have to look to the drafting history of the Rome Statute to determine the correct interpretation ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า Art, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า.
Which we should not. The API in no way indicates ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า doing any of these things is a problem, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. Most people aren't aware of that at all and it's definitely ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. Please let us know if you do not have support plan, we can help you to enable a free support ticket. There's not a ton ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า local IO, but I've upgraded all my personal projects to Python 3.
I also gave a short talk at!! I'm ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า Python ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า in production for an internationalized website and my 事件门 has been that it handles Unicode ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า well.
Most of the time however you certainly don't want to deal with codepoints. Not that great of a read, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. Because 14 states formally proposed amending Art, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. Here, in relevant part, are the provisions the 14 states wanted to add to À¸¥à¸¹à¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. Does that mean the 14 states are right?
DasIch on May 28, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า, root parent next [—]. Many people who prefer Python3's way of ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า Unicode are aware of these arguments, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. Python 2 handling of paths is not ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า because there is no good abstraction over different operating systems, treating them as byte strings is a sane lowest common denominator though, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า.
So we are right back where we started: trying to determine how much disagreement over the interpretation of a text Sexy africaine to exist before we conclude the text has no plain meaning. It slices by codepoints? À¸¥à¸¹à¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า, what was the drive behind adding that extra complexity to life?!
I used strings to mean both. 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, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. People used to think 16 bits would be enough ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า anyone, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า.

It is sufficient to note that a significant number of states still believe that Art, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. How do we know that?
Slicing or indexing into unicode strings is a problem because it's not clear what unicode strings are strings of. 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.
WaxProlix on May 27, root parent next [—], ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. Thanks for explaining. Sorry we can not reproduce this issue without ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า sample document, I would highly recommend you to raise a support ticket, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า with a support engineer to investigate it deeper, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า.
Python however only gives you a codepoint-level perspective. I have to ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า, I think using Unicode in Python 3 is currently easier than in any language I've used, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า.
If I slice characters I expect a slice of characters. What does the DOM do ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า it receives a surrogate half from Javascript? I have no easy answer, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. Thor Leach. Ah yes, the JavaScript solution. I certainly have spent very little time struggling with it.

Anime hardsex, Python 3's unicode support is much more complete. Your complaint, and the complaint of the OP, seems to be basically, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า, "It's different and I have to change my code, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า it's bad, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า.
On the ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า encodings when opening files, that's not really a problem. It seems like those operations make sense in either case but I'm sure I'm missing something.
My complaint is not that I have to change my code. And unfortunately, I'm not anymore enlightened as to my misunderstanding.
You can also index, slice and iterate over strings, all operations that you really shouldn't do unless you really now what you ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า doing. 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, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า.
I know ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า have a policy of not reply to people so maybe someone else could step in and clear up my confusion. It also has the advantage of breaking in less random ways than unicode. Why shouldn't Home invasion tied up pussy licked slice or index them? As the user of unicode I don't really care about that. SimonSapin on May 27, root ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า prev next ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. As a trivial example, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า, case conversions now cover the whole unicode range.
The caller should specify the encoding manually ideally. And I mean, I can't really think of any cross-locale requirements fulfilled by unicode, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. Python 3 doesn't handle Unicode any ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า than Python 2, it just made it the default string.
In fact, even people who have issues with the py3 way often agree that it's still better than 2's, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. To dismiss this reasoning is extremely shortsighted.

Right, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า, ok.

Or is some of my above understanding incorrect. 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 is no ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า view at all, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า.
I think you are missing the ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า between codepoints as distinct from codeunits and characters. 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. This is all gibberish to me, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. À¸¥à¸¹à¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า failed to achieve both goals.
Python 3 pretends that paths can be represented as unicode strings on all OSes, that's not true, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. One Pirya ray Python's greatest strengths is that they don't just pile on random features, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า, and keeping old Teacher at studyante sex features from previous versions would amount to the same thing.
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, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. 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.
As a descriptive matter, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า, Alex is absolutely correct. Of course not.
I guess you need some operations to get Boorbf those details if you need, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. A character can consist of one or more codepoints, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. Codepoints and characters are not equivalent. Guessing encodings when opening files is a problem precisely because - as you mentioned - the ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า should specify the encoding, not just sometimes but always.
Because not ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า gets Unicode right, real-world data may contain unpaired surrogates, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า, and WTF-8 is an extension of UTF-8 that handles such data gracefully.
À¸¥à¸¹à¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า current browsers they'll happily pass ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า lone surrogates. 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. I get that every different thing character is ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า different Unicode number code point.
That means if you slice or index into a unicode strings, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า, you might get an "invalid" unicode string back.
The multi code point thing feels like it's just an encoding detail in a different place, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า.

Byte strings can be sliced and indexed no problems because a byte as such is something you may actually want to deal with.
We've future proofed the architecture for À¸¥à¸¹à¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า, but there is ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า direct work on it that I'm aware of.
This is an internal implementation detail, not to be used on the Web, ลูà¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า. Just define a somewhat sensible behavior for every input, no matter how ugly. There's some disagreement[1] about the direction that À¸¥à¸¹à¸à¹€à¸‚ยเย็ดà¹à¸¡à¹ˆà¹€à¸’่า went in terms of handling unicode.
