使用C等语言进行编程中的字符编码

[英]Character encoding in programming with languages such as C

原文 2011-12-11 14:06:05 1 2 c/ ascii/ utf

Having read tutorials and books on C, I am trying hard to connect my knowledge of UTF (as the text format for roman letters and all sorts of other alphabets/scripts) with C, as a programming language used all over the world. 阅读了有关C的教程和书籍之后，我努力将我对UTF的知识（罗马字母和各种其他字母/脚本的文本格式）与C进行连接，C作为一种在世界范围内使用的编程语言。

C seems to take ASCII characters. C似乎采用ASCII字符。

So if I wanted to write a program with input/output in Chinese,say, how would I implement this with C? 因此，如果我想用中文编写一个带有输入/输出的程序，那我怎么用C来实现呢？

You would be using "wide char" wchar instead of char . 您将使用“ wide char” wchar而不是char 。

There are also specialized libraries like iconv that help on some platforms. 还有一些像iconv这样的专业库，在某些平台上有帮助。

It's character encoding , not text formatting . 它是字符编码 ，而不是文本格式 。 If you want to use UTF in C, you can use a library to handle it (see eg here for UTF-8 libraries: Light C Unicode Library ). 如果要在C中使用UTF，则可以使用一个库来处理它（例如，对于UTF-8库，请参见此处： Light C Unicode Library ）。 If you're writing a GUI program, your GUI library probably has facilities to handle it (GTK, KDE, wxWidgets and Tk all support Unicode). 如果要编写GUI程序，则GUI库可能具有处理它的功能（GTK，KDE，wxWidgets和Tk均支持Unicode）。
