In the past two days, I took the time to summarize/sort out the actual encoding methods and usage of various encodings in Java applications. I will record them here for future reference. In order to form a complete understanding and in-depth

C ++ does not support Unicode, even utf8, unicodeutf8So far, unicode is a common sense, but it is still a headache for some programming languages with a long history. Without the support of third-party libraries, C ++ does not actually effectively

Java developers must keep in mind that characters exist only in one form in Java, which is Unicode (no specific encoding is selected, directly using their numbering in the character set, which is the only way to unify). Because Java uses Unicode

VarThe following methods are commonly used in the conversion of such data to Chinese issues.1. Eval parsing or new Function ("' + str + ')" ()// "I am a Unicode encoding"2. Unescape parsing// "I am a Unicode encoding" C # Chinese and Unicode
