unicode

问题 when I read data from Stream API of twitter and then write to xmlfile. But some special character like &#55357; will cause error (I mean when I open that xmlfile in Chrome, Chrome said that there was an error at that character!) I want to convert that encoded sequence ( &#55357; ) into real character () before writing to xmlfile! How to implement this? -------------ADDED-------------- This is the XMLFile content: <?xml version="1.0" encoding="UTF-8"?> <root> <text>@carlyraejepsen would be a

问题 I am trying to add Unicode support to a program that I wrote. My ASCII code compiled and had the following lines: std::stringstream stream("abc"); std::istream_iterator<std::string> it(stream); I converted this to: std::wstringstream stream(L"abc"); std::istream_iterator<std::wstring> it(stream); I get the following error in the istream_iterator constructor: error C2664: 'void std::vector<_Ty>::push_back(std::basic_string<_Elem,_Traits,_Alloc> &&)' : cannot convert parameter 1 from 'std:

问题 I need to convert unicode string to unicode characters. for eg:Language Tamil "கமலி"=>'க','ம','லி' i'm able to strip unicode bytes but producing unicode characters is became problem. byte[] stringBytes = Encoding.Unicode.GetBytes("கமலி"); char[] stringChars = Encoding.Unicode.GetChars(stringBytes); foreach (var crt in stringChars) { Trace.WriteLine(crt); } it gives result as : 'க'=>0x0b95 'ம'=>0x0bae 'ல'=>0x0bb2 'ி'=>0x0bbf so here the problem is how to strip character 'லி' as it as 'லி'

问题 Reading the Wikipedia article on UTF-8, I've been wondering about the term overlong . This term is used various times but the article doesn't provide a definition or reference for its meaning. I would like to know if someone can explain the term and its purpose. 回答1: It's an encoding of a code point which takes more code units than it needs to. For example, U+0020 is represented in UTF-8 by the single byte 0x20 . If you decode the two bytes 0xc0 0xa0 in the normal fashion, you'll still end up

问题 I was testing two almost identical regexes against a string (on regex101.com), and I noticed that there was a huge difference in the number of steps that they were taking. Here are the two regexes: (Stake: £)(\d+(?:\.\d+)?) (winnings: £)(\d+(?:\.\d+)?) This is the string I was running them against (with modifiers g , i , m , u ): Start Game, Credit: £200.00game num: 1, Stake: £2.00Spinning Reels:NINE SEVEN KINGKING STAR ACEQUEEN JACK KINGtotal winnings: £0.00End Game, Credit: £198Start...

问题 I am looking for a way to print unicode characters to a UTF-8 aware Linux console, using Python 2.x's print method. What I get is: $ python2.7 -c "print u'é'" é What I want: $ python2.7 -c "print u'é'" é Python detects correctly that the console is configured for UTF-8. $ python2.7 -c "import sys; print sys.stdout.encoding" UTF-8 I have looked at 11741574, but the proposed solution uses sys.stdout , whereas I am looking for a solution using print . I have also looked at 5203105, but using

问题 EDIT: As suggested special chars are displayed correctly if I use notepad++ to open the csv file. They are displayed correctly too when I import the csv file into excel. How can I generate a csv file that is displayed correctly when opened by excel since file importing is not an option for the users I'm generating a csv file that is being processed using Excel. Special caracters like 'é' are not displayed properly when the file is opened with excel This the poc I'm using to generate the csv

问题 I am trying to parse utf-8 strings into "bite sized" segments. For example, I would like to break down a text into "sentences". Is there a comprehensive collection of characters (or regex) that correspond to end of sentences in all languages? I'm looking for something that would capture the Latin period, exclamation and interrogation marks, the Chinese and Japanese full stop, etc. Something like the above but for the equivalent of a comma would be great too. 回答1: I haven’t encountered any
