utf-8

问题 A user can copy and paste into a textarea html input and sometimes is pasting invalid UTF-8 characters, for example, a copy and paste from a rtf file that contains tabs. How can I check if a string is a valid UTF-8? 回答1: I think you misunderstand what "UTF-8 characters" means. UTF-8 is an encoding of Unicode which can represent pretty-much every single character and glyph that has ever existed in recorded human history, so that extent there are no "invalid" UTF-8 characters. RTF is a

问题 I have a problem with the values inserted in all my <h:inputText> fields. Some characters are not encoded in the right way. E.g. if I put ciò in the input field I get ciò . How can I allow a user to insert text with those characters and save them correctly? The problem in not in the DB encoding since I already have the wrong value before inserting it in the DB. I'm using JSF 2 with Facelets and GlassFish as application server. 回答1: You need to tell Glassfish to use UTF-8 to decode paramters

问题 I'm trying to convert to unicode and create some unit tests to ensure that unicode is working. Here is my current code, which fails on the mb_detect_encoding() line, and which I'm also not sure whether it is a valid test of unicode support: function testMultiLingualEncodings(){ // Create this string via a heredoc. $original = ' A good day, World! Schönen Tag, Welt! Une bonne journée, tout le monde! يوم جيد، العالم 좋은 일, 세계! Một ngày tốt lành, thế giới! こんにちは、世界！ '; // Contains international

问题 I am redirecting std::wclog to a file for logging in my program: std::wclog.rdbuf((new std::wofstream("C:\\path\\to\\file.log", std::ios::app))->rdbuf()); Logging happens by writing to std::wclog : std::wclog << "Schöne Grüße!" << std::endl; Surprisingly I found that the file is being written in ANSI. (This would be totally acceptable for ofstream and clog , but I had expected wofstream and wclog to produce some kind of unicode output.) I want to be able to log in CYK langugages as well (e.g.

问题 I have ran into a peculiar problem with NSXMLParser. For some reason it cuts out all the characters in front of all the norwegian characters æ, ø and å. However, the problem seems to be the same with all non a-z characters.(All foreign characters) Examples: Reality: Mål Output: ål Reality: Le chant des sirènes Output: ènes Heres an example from the log where I have printed out the string from: - (void) parser:(NSXMLParser *)parser foundCharacters:(NSString *)string Log: 2012-02-22 14:00:01

问题 It's been quite a while since I'm banging my head against this: multipart/mixed content. @RequestPart(name="view") CoolView, @RequestPart(name="files") Part [] files Also using spring's (it does not matter because CommonsMultipartResolver fails too) : StandardServletMultipartResolver Now the thing is that when uploading files that have some names outside US_ASCII characters, the server is converting them into something weird. And by weird I mean it converts them to ISO_8859_1, and I think I

问题 I'm trying to get the output of a command in PowerShell and encode it and then decode it again to receive the results of the said command as shown. $enc = [system.Text.Encoding]::UTF8 $bytes = $enc.GetBytes((Invoke-Expression "net users")) $enc.GetString($bytes) However, the result comes out malformed as opposed to the original net users command. I've tried changing the encodings to ASCII and Unicode and still the result is malformed. Any ideas on how to maintain the formatting? 回答1: The

问题 I am using RMySQL to connect to an aws MySQL server. It works, except character values are deformed. This question has been asked before but the fixes don't seem to work for me. Here's what I'm doing: Make sure no connections are open: dbListConnections(MySQL()) list() Make sure my connection is set to use UTF-8: dbGetQuery(credentials, "show variables like 'character_set%'") Variable_name Value 1 character_set_client utf8 2 character_set_connection utf8 3 character_set_database utf8 4
