More importantly some codepoints merely modify others and cannot stand ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ their own, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. 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.

Mojibake - Wikipedia
Two of the most common applications in which mojibake may occur ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ web browsers and word processors, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. 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, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
Therefore, the concept of Unicode scalar value was introduced and Unicode text was restricted to not contain any surrogate code point. Icelandic has ten possibly confounding characters, and Faroese has eight, making many words almost completely unintelligible when corrupted e. There Python 2 is only "better" in that issues will probably fly under the radar if you don't prod things too much.
Fortunately it's not something I deal with often but thanks for the info, will stop me getting caught out later. The multi code point thing feels like it's just an encoding detail in a different place. There is no coherent view at all. This way, even though the reader has to guess what ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ original letter is, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, almost ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ texts remain legible.
DasIch on May 28, root parent next [—]. Pretty unrelated but I was thinking about efficiently encoding Unicode a week or two ago. Your recently viewed items and featured recommendations.
The numeric value of these code units denote codepoints that lie themselves within the BMP, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. Because we want our encoding schemes to be equivalent, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ Unicode code space contains a hole where these ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ surrogates lie, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
This is all gibberish to me. Ah yes, the JavaScript solution. The difficulty of resolving an instance of mojibake varies depending on the application within which it occurs and the causes of it. Mojibake also occurs when the encoding is incorrectly specified.
Get to Know Us. Make Money with Us. Amazon Payment Methods, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. These two characters can ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ correctly encoded in Latin-2, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, Windows, and Unicode, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. That is, you can jump to the middle of a stream and ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ the next code ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ by looking at no more than 4 bytes.
On the guessing encodings when opening files, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, that's not really a problem. The API in no way indicates that doing any of these things is a problem. Mojibake is often ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ with text data that have been tagged with a Teenage girl on girl encoding; ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ may ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ even be tagged at all, but moved between computers with different default encodings.
I think there might be some value in a fixed length encoding but UTF seems a bit wasteful. DasIch on May 27, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, root parent next [—], ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
The WTF-8 encoding | Hacker News
Examples of ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ include Windows and ISO When there are layers of protocols, each trying to specify the encoding based on different information, the least certain information may be misleading to the recipient. For some writing systemssuch as Japaneseseveral encodings have historically سكس عل الكام employed, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, causing users to see mojibake relatively often.
It also has the advantage of breaking in less random ways than unicode. Browsers Mom and son bbw xxx allow a ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ to change their rendering engine's encoding setting on ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ fly, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, while word processors allow the user to select the appropriate encoding when opening a file. And š§ï¸âš§ï¸âš§ï¸âš§ï¸ mean, I can't really think of ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ cross-locale requirements fulfilled by unicode.
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, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. For example, attempting to view non-Unicode Cyrillic text using a font that is limited to the Latin ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, or using the default "Western" encoding, typically results in text that ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ almost entirely of vowels with diacritical marks e, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
We would never run out of codepoints, and lecagy applications can simple ignore codepoints it doesn't understand. 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 requires all ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ extra shifting, dealing with the potentially partially filled last 64 bits and encoding and decoding to and from the external world.
Depending on the type of software, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, the typical solution is either configuration or charset detection heuristics. Good examples for that are paths and anything that relates to local IO when you're locale is C. Maybe ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ has been ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ experience, but it hasn't been mine.
While a few encodings are ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ to detect, such as UTF-8, there are many that are hard to distinguish see charset detection. The character set may be communicated to the client in ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ number of 3 ways:. Byte strings can be sliced and indexed no problems because a byte as such is something you may actually want to deal with. Users of Central and Eastern European languages can also be affected, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
Right, ok, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. This was gibberish to me too. Or China mom force porn some of my above understanding incorrect.
Some computers did, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, in older eras, have vendor-specific encodings which caused mismatch also for English text. I think you are missing the difference ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ codepoints as distinct from codeunits and characters. Bytes still have methods like. Whereas Linux distributions mostly switched to UTF-8 in⚧ï¸âš§ï¸âš§ï¸âš§ï¸, [2] Microsoft Windows generally uses UTF, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, and sometimes uses 8-bit code pages for text files in different languages.
The caller should specify the encoding manually ideally.
" " symbols were found while using contentManager.storeContent() API
Man, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, what was the drive behind adding that extra complexity to life?! Why wouldn't this work, apart from already existing applications that does not know how to do this. š§ï¸âš§ï¸âš§ï¸âš§ï¸ shouldn't you slice or index them? I know you have a policy of not reply to people so maybe someone else could step in and clear up my confusion. However, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, digraphs are useful ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ communication with other parts of the world, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
With Unicode ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ 21 But would it be worth the hassle for example as ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ encoding in an operating system? Likewise, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, many early operating systems do not support multiple encoding formats and thus will end up displaying mojibake if made to display non-standard text—early versions of Microsoft Windows and Palm OS for example, are localized on a ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ basis and will only support encoding standards relevant to the country the localized version will be sold in, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, and will display mojibake if a file containing a text in a different encoding format from the version that the OS is designed to support is opened.
Before Unicode, it was necessary to match text encoding with a font ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ the same encoding system.
I guess you need some operations to get to those details if you need. 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, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. Simple compression can take care of the wastefulness of using excessive space to encode text - so it really only leaves efficiency.
To correctly reproduce the original text that was encoded, the correspondence between the encoded data and the notion of its encoding must be preserved i. Python however only gives you a codepoint-level perspective. Thanks for explaining.
For Unicode, one solution is ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ use a byte order mark⚧ï¸âš§ï¸âš§ï¸âš§ï¸, but for source code and other machine readable text, many parsers do not tolerate this. The differing default settings between computers are in part due to differing deployments of Unicode among operating system families, and partly the legacy encodings' specializations for different writing systems of human languages.
Even so, changing the operating system encoding settings is not possible on earlier operating systems such as Windows 98 ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ to resolve this issue on earlier operating systems, a user would have to use third party font rendering applications, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. Now we have a Python 3 that's incompatible to Python 2 ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ provides almost no significant benefit, solves none of the large well known problems and introduces quite a few new problems, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
File systems that support extended file attributes ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ store this as user. The latter practice seems to be better tolerated in the German language sphere than in the Nordic countries, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
SimonSapin on May 27, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, parent prev next [—]. When you say "strings" are you referring to strings or bytes?
See combining code ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. We would only waste 1 bit per byte, which seems reasonable given just how many ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ encoding usually represent. UTF-8 also has the ability to be directly recognised by a simple algorithm, so that well written software should be able to avoid mixing UTF-8 up with other encodings.
However, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, ISO has been obsoleted by two competing standards, the backward compatible Windows ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, and ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ slightly altered ISO However, with the advent of UTF-8mojibake has become more common in certain شابان يغتصبون Ùتاه بلقوه, e. As a trivial example, case conversions ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ cover the whole unicode range.
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.
O 1 indexing of code points is not that useful because code points are not what people think of as "characters". Codepoints and characters are not equivalent. Veedrac on May 27, root parent prev next [—]. It slices by codepoints? On further thought I agree. They failed to achieve both ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. The character table contained within the display firmware will be localized to have characters for the country the device is to be sold in, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, and typically ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ table differs from country to country.
Most people ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ aware of that at all and it's definitely surprising. There's not a ton of local IO, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, but I've upgraded all my personal ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ to Python 3. If the encoding is not specified, it is up to the software to decide it by other means.
Modern browsers and word processors often support a wide array of character encodings. That's just silly, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, 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 ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. As the user of unicode I don't really care about that.
A major source of trouble are communication protocols that rely on ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ on each computer rather than sending or storing metadata together with the data, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. This often happens between encodings that are similar.
People used to think 16 bits would be enough for anyone. In Windows XP or later, a user also has the option to use Microsoft AppLocale⚧ï¸âš§ï¸âš§ï¸âš§ï¸, an application that allows the changing of per-application locale settings.
I get that every different thing character is a different Unicode number code point. And ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, I'm not anymore enlightened as to my misunderstanding. Audible Download Audiobooks, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. How is any of that in conflict with my original points? Can someone explain this in laymans terms? 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.
Python 3 pretends that ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ can be represented as unicode strings on all OSes, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ not true, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. But UTF-8 has the ability to be directly recognised by a simple algorithm, so that well written software should be able to avoid mixing UTF-8 up with other encodings, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, so this was ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ common when many had software not supporting UTF In Swedish, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, Norwegian, Danish and German, vowels are rarely repeated, and it is usually obvious when one character gets corrupted, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, e.
It certainly isn't perfect, but it's better than the alternatives. Using code page to view text in KOI8 or vice versa results in garbled text that consists mostly of capital letters KOI8 and codepage share the same ASCII region, but KOI8 has uppercase letters in the region where codepage has lowercase, and vice versa.
As mojibake is the instance of non-compliance between these, it can be achieved by manipulating the data itself, or just relabelling it, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. That is a unicode string that cannot be encoded or rendered in any meaningful way. These are languages for which the ISO character set also known as Latin 1 or Western has been in use, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. That means if you slice or index into a unicode strings, you might get an "invalid" unicode string back.
As such, these systems will potentially display mojibake when loading text generated on a system from a different country. On top of that implicit coercions have been replaced with implicit broken guessing of encodings for example when opening files, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. Because not everyone gets Unicode right, real-world ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ may contain unpaired surrogates, and WTF-8 is an extension of UTF-8 that handles such data gracefully.

Most of the time however you certainly don't want to deal with codepoints. 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, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
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. SiVal on May 28, parent prev next [—], ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. You ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ look at unicode strings from different perspectives and see a sequence of ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ or a sequence of characters, both can be reasonable ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ on what you want to do.
If I slice characters I expect a slice of characters. That was the piece I was missing. In this case, the user must change the operating system's encoding settings to match that of the game. Every term is linked to its definition. If you don't know the encoding of the file, how can you decode it? The Sofiya ansari fucking – XXX Videos characters are typically the ones that become corrupted, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, making texts only mildly unreadable with mojibake:.
However, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, changing the system-wide encoding settings can also cause Mojibake in pre-existing applications, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
Therefore, the assumed encoding is systematically wrong ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ files that come from a computer with a different setting, or even from a differently localized software within the same system.
Slicing or indexing into unicode strings is a problem because it's not clear what unicode Cewe digilir are strings of, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
If was to make a first attempt at a variable length, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ well defined backwards compatible encoding scheme, I would use something ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ the number of bits upto and ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ the first 0 bit as defining the number of bytes used for this character. It seems like those operations make sense in either case but I'm sure I'm missing something.
A character can consist of one or more codepoints. The problem gets more complicated when it occurs in an application that normally does not support a wide range of character encoding, such as in a non-Unicode computer game.
Your complaint, and the complaint of the OP, seems to be basically, "It's different and I have to change my code, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ it's bad, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
It may take some trial and error for users to find the correct encoding. The situation began to improve when, after pressure from academic and user groups, ISO succeeded as the ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ standard" with limited support of ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ dominant vendors' software today largely replaced by Unicode.
Yes, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, "fixed length" is misguided.
You could still open it as raw ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ if required. I understand that for efficiency we want this to be as fast as possible. Is the desire for a fixed length Mikayla campionas misguided because indexing into a string is way less common than it seems? There's no good use ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. Well, Python 3's unicode support is much more complete.
Guessing encodings when opening files is a problem precisely because - as you mentioned - the caller should specify the encoding, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, not just sometimes but always.
My complaint is not that I have to change my code, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
The encoding of text files is affected by locale ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, which depends on the user's language, brand ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ operating system⚧ï¸âš§ï¸âš§ï¸âš§ï¸, and many other conditions, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
I have to disagree, I think using Unicode in Python 3 is ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ easier than in any language I've used.
Most recently, the Unicode encoding includes code points for practically all the characters of all the world's languages, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, including all Cyrillic characters, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. Failure to do this produced unreadable gibberish whose specific appearance varied depending on the exact combination of text encoding and font encoding, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸.
Polish companies selling early DOS computers created their own mutually-incompatible ways to encode Polish characters and simply reprogrammed the EPROMs of the video cards typically CGAEGA⚧ï¸âš§ï¸âš§ï¸âš§ï¸, Rashal kolenci Hercules to provide hardware code pages with the needed glyphs for Polish—arbitrarily located without reference to where other computer sellers had placed them.
Much older hardware is typically designed to support only one character set and the character set typically cannot be altered. I used strings to mean both, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸. 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.
Guessing an encoding based on the locale or the content of the file should be the exception and something the ⚧ï¸âš§ï¸âš§ï¸âš§ï¸ does explicitly. š§ï¸âš§ï¸âš§ï¸âš§ï¸ example, in Norwegian, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, digraphs are associated with archaic Danish, and may be used jokingly.
For example, ⚧ï¸âš§ï¸âš§ï¸âš§ï¸, the Eudora email client for Windows was known to send emails labelled as ISO that were in reality š§ï¸âš§ï¸âš§ï¸âš§ï¸ Of the encodings still in common use, many originated from taking ASCII and appending atop it; as a result, these encodings are partially compatible with each other.

I certainly have spent very little time struggling with it. š§ï¸âš§ï¸âš§ï¸âš§ï¸ are prone to mis-prediction.
