问题 It seems like a rather complicated issue to work with std::string and UTF8 and I cannot find a good explanation of do's and dont's. How can I properly work with UTF8 in C++? It is rather confusing. I've found boost::locale and I set the global locale: std::locale::global(boost::locale::generator()("")); However, after this what do I need to think about, when can I get problems? Will writing/reading from file work as expected, string comparisons etc...? So far I'm aware of the following: std:

问题 java.sql.SQLException: Incorrect string value: '\xAC\xED\x00\x05sr...' for column 'xxxx' The column is a longtext in MYSQL with utf8 charset and utf8_general_ci collation. What is wrong? 回答1: It's a bit late, but you might want to know that \xAC\xED\x00\x05sr... is a magic number for Java serialization. Apparently your parameter is being serialized instead of being pasted as a string. 回答2: Assuming that those are hexadecimal escape codes, the text \xAC\xED\x00\x05sr... is not a valid UTF-8

问题 I've read quite a bit on the topic already, including what seems to be the definitive guide on this topic here: http://docs.python.org/howto/unicode.html Perhaps for a more experienced developer, that guide may be enough. However, in my case, I'm more confused than when I started and still haven't resolved my issue. I am trying to read filenames using os.walk() and to obtain certain information about the files (such as filesize) before writing that information to a text file. This works as

问题 I use MSBuild.exe for building solution on machine with russian language. But in TeamCity build log all russian chars in wrong encoding. How to setup MSBuild.exe for properly output (UTF-8 for example)? 回答1: Check /fileloggerparameters command line parameter here. It should be the same for console logger. e.g. MyLog.log file with diagnostic verbosity using UTF-8 encoding: /fileLoggerParameters:LogFile=MyLog.log;Encoding=UTF-8;Verbosity=diagnostic 来源： https://stackoverflow.com/questions

问题 What is the difference between UTF-32 and UCS-4 ? Isn't UTF-32 supposed to be a fixed-width encoding ? 回答1: UTF-32 has started as a subset of UCS-4 . Now it is identical except that the UTF-32 standard has additional Unicode semantics. See details on wikipedia: The original ISO 10646 standard defines a 31-bit encoding form called UCS-4 , in which each encoded character in the Universal Character Set (UCS) is represented by a 32-bit friendly code value in the code space of integers between 0

问题 I've read in several stackoverflow answers that some characters do not directly map (or are even "unmappable") when converting from Cp1252 (aka Windows-1252; they're the same, aren't they?) to UTF-8, e.g. here: https://stackoverflow.com/a/23399926/2018047 Can someone please shed some more light on this? Does that mean that if I batch/mass convert source code from cp1252 to utf-8 I'll get some characters that will end up as garbage? 回答1: This is how Windows 1252 codepage looks like. As you can

问题 I'm trying to send data as UTF-8 over Ajax, but it's changing some data in unicode . I'll explain it with two short examples: A simple POST (without ajax) <form accept-charset="UTF-8" method="POST" action="test2.php"> <input type="text" class="" name="text"> <input type="submit" class="button" value="Submit"> </form> Meta and PHP headers are always set: <meta charset="utf-8"> header("Content-Type: text/html; charset=utf-8"); If I submit an Arabic letter ( ب ), and use strlen() it will return

问题 There are several unicode relevant questions has been confusing me for some time. For these reasons as follow I think the unicode characters are existed on disk. Execute echo "\u6211" in terminal, it will print the glyph corresponding to the unicode code point U+6211. There's a concept of UCD (unicode character database), and We can download it's latest version. UCD latest Some new version unicode characters like latest emojis can not display on my mac until I upgrade macOS version. So if the
