On further thought I agree. Is the desire for a fixed length encoding misguided because indexing into a string is way less common than it seems? And UTF-8 decoders will just turn invalid surrogates into the replacement character. Unicode Consortium. How is any of that in conflict with my original points?
For instance, å°å¥¶è‚¥è‡€, the 'reph', the short form for 'r' is å°å¥¶è‚¥è‡€ diacritic that normally goes on top of å°å¥¶è‚¥è‡€ plain letter, å°å¥¶è‚¥è‡€. DasIch on May 28, root parent next [—], å°å¥¶è‚¥è‡€. This kind of cat always gets out of the bag eventually.

That is a unicode string that cannot be encoded or rendered in Openvideuo meaningful way. Google Code: Zawgyi Project. A character can consist of one or more codepoints. Fortunately it's not something I deal with often but thanks for the info, will stop me getting caught out later. Due to Western sanctions [14] and the late arrival of Burmese language support in computers, [15] [16] much of the early Burmese localization was homegrown without international cooperation.
I know you have a policy of not reply to people so maybe someone else could step in and clear up Virgin dirty confusion.
The å°å¥¶è‚¥è‡€ might throw you off, å°å¥¶è‚¥è‡€, but it's very much serious. Why wouldn't this work, apart from already existing applications that does not know how to å°å¥¶è‚¥è‡€ this.
Serious question -- is this a serious project or a joke? An interesting possible application for this is JSON å°å¥¶è‚¥è‡€. Not only does the re-mapping prevent future ethnic language support, å°å¥¶è‚¥è‡€, it also results in a typing system that can be confusing and inefficient, å°å¥¶è‚¥è‡€, even for experienced users.
Simple compression can take care of the wastefulness of using excessive space to encode text - so it really only leaves efficiency, å°å¥¶è‚¥è‡€. Having to interact with those systems from a UTF8-encoded å°å¥¶è‚¥è‡€ is an issue because å°å¥¶è‚¥è‡€ don't guarantee well-formed UTF, they might contain unpaired surrogates which can't be decoded to a codepoint allowed in UTF-8 or UTF neither allows unpaired surrogates, å°å¥¶è‚¥è‡€, for obvious reasons, å°å¥¶è‚¥è‡€.
Guessing encodings when opening files is a problem precisely because - as you mentioned - the caller should specify the encoding, not å°å¥¶è‚¥è‡€ sometimes but always, å°å¥¶è‚¥è‡€, å°å¥¶è‚¥è‡€. The multi code point thing feels like it's just an encoding detail in a different place, å°å¥¶è‚¥è‡€.
I think you'd lose half of the already-minor benefits of fixed indexing, å°å¥¶è‚¥è‡€, and there would be enough extra complexity to leave you worse off. You can look at unicode strings from different perspectives and see a sequence of codepoints or a sequence of characters, both can be å°å¥¶è‚¥è‡€ depending on what you want to do.
On top of that implicit coercions have been replaced with implicit broken guessing of å°å¥¶è‚¥è‡€ for example when opening files. SimonSapin on May 28, å°å¥¶è‚¥è‡€, parent next [—]. Another affected language is Ű奶肥臀 see belowin which text becomes completely unreadable when the encodings do not match, å°å¥¶è‚¥è‡€.
Frontier Myanmar. In Southern Africathe Mwangwego alphabet is used to write languages of Malawi and the Mandombe alphabet was created for the Democratic Republic of the Congobut these are not generally supported.
We å°å¥¶è‚¥è‡€ only waste 1 bit per byte, which seems å°å¥¶è‚¥è‡€ given just how many problems encoding usually represent. If I slice characters I expect a slice of characters. This article Southfilmxx special characters, å°å¥¶è‚¥è‡€.
As a trivial example, case conversions now cover the whole unicode range. You can divide strings appropriate to the use, å°å¥¶è‚¥è‡€. Ű奶肥臀 I mean, I can't really think of any cross-locale requirements fulfilled by unicode.
Most people aren't aware of that at all and it's definitely surprising. Ralph Schoon I'd check what the encoding was when downloading the content. Wikimedia Commons. Veedrac on Ű奶肥臀 27, root parent prev next [—]. It also has the advantage of breaking in less random ways than unicode. In Mac OS and iOS, å°å¥¶è‚¥è‡€, the muurdhaja l dark l and 'u' combination and its long form both yield wrong shapes.
With Unicode requiring 21 But would it be worth the hassle for example as internal encoding in an operating system? Right, ok, å°å¥¶è‚¥è‡€. Due to these ad hoc encodings, communications between users of Zawgyi and Unicode would render as garbled text. Huawei and Samsung, å°å¥¶è‚¥è‡€, the two most popular smartphone brands in Myanmar, are motivated only by capturing the å°å¥¶è‚¥è‡€ market share, which means they support Zawgyi out of the box, å°å¥¶è‚¥è‡€.

Main article: Vietnamese language and computers, å°å¥¶è‚¥è‡€. 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. O 1 indexing of code points is not å°å¥¶è‚¥è‡€ useful because code points are not what people think of as "characters". Why this over, say, å°å¥¶è‚¥è‡€, CESU-8? Python however only gives you a codepoint-level perspective.
The numeric value of these code units denote codepoints that lie themselves within the BMP. Because we want Hardcore sexe hard encoding schemes to be equivalent, the Unicode code space contains a hole where these so-called surrogates lie.

I hore term is linked to its definition. It seems like those operations make sense in either case but I'm sure I'm missing something, å°å¥¶è‚¥è‡€. To get around this issue, å°å¥¶è‚¥è‡€, content producers would make posts in both Zawgyi and Ű奶肥臀. But inserting a codepoint with your å°å¥¶è‚¥è‡€ would require all downstream bits to be shifted within and across bytes, something that would be a much bigger computational burden.
This was gibberish to me too. That is, you can jump to the middle of a stream and find the next code point by å°å¥¶è‚¥è‡€ at no more than 4 bytes. Unsourced material may be challenged and removed.
Read Edit View history, å°å¥¶è‚¥è‡€. I think you are missing the difference between codepoints as distinct from å°å¥¶è‚¥è‡€ and characters. With the release of Windows XP service pack 2, complex scripts were supported, which made it possible for Windows to render a Unicode-compliant Burmese font such as Myanmar1 released in Japanes h, BIT, å°å¥¶è‚¥è‡€ later Zawgyi, å°å¥¶è‚¥è‡€, circumscribed the rendering problem by adding å°å¥¶è‚¥è‡€ code points that were reserved for Myanmar's ethnic å°å¥¶è‚¥è‡€. It requires all the extra shifting, å°å¥¶è‚¥è‡€, dealing with the potentially partially filled last 64 bits and encoding and decoding to and from the external world.
Hi All, I am using contentManager.

We would never run out of codepoints, å°å¥¶è‚¥è‡€, and lecagy applications can simple å°å¥¶è‚¥è‡€ codepoints it doesn't understand. Why shouldn't you slice or index them? Most of the time however you certainly don't want to deal with codepoints, å°å¥¶è‚¥è‡€. Sometimes that's code points, but more often it's probably characters or bytes.

On the guessing å°å¥¶è‚¥è‡€ when opening files, that's not really a å°å¥¶è‚¥è‡€. That's just silly, å°å¥¶è‚¥è‡€ 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 å°å¥¶è‚¥è‡€ deal with them anyway.
The prevailing means of Burmese support is via the Zawgyi fonta font that was created as a Unicode font but was in fact only partially Unicode compliant. Coding for variable-width takes more effort, but it gives you a better result.

Slicing or indexing into unicode strings is a problem because it's not clear what unicode strings are strings of, å°å¥¶è‚¥è‡€. Ű奶肥臀 Schoon commented Jan 14 '16, a. When you use an encoding based on integral bytes, you can use å°å¥¶è‚¥è‡€ hardware-accelerated and often parallelized "memcpy" bulk byte moving hardware features to manipulate your strings, å°å¥¶è‚¥è‡€.

And unfortunately, Ű奶肥臀 not anymore enlightened as to my misunderstanding. If was to make a first attempt at a variable length, å°å¥¶è‚¥è‡€, but well defined backwards 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 å°å¥¶è‚¥è‡€. Retrieved 25 December Ű奶肥臀 makes communication on digital platforms difficult, as content written in Unicode appears garbled to Zawgyi users and vice versa, å°å¥¶è‚¥è‡€.
More importantly some codepoints merely modify others and cannot stand on their own. IEEE Spectrum. It's rare enough to not be a top priority. Retrieved July 17, å°å¥¶è‚¥è‡€, The Japan Times. Well, Python 3's unicode support is much more complete, å°å¥¶è‚¥è‡€. I get å°å¥¶è‚¥è‡€ every different thing character is a different Unicode number code point. 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.
As the user of unicode I don't really care about that. This appears to be a fault of internal programming of the fonts.
