The setlocale function of Win32 API configures the localized information function

Setlocale:
Function prototype: char * setlocale (INT category, const char * locale );
Header file: <locale. h>
Supported Operating Systems: ANSI, Win 95, Win NT
You can use the following settings for simplified Chinese: setlocale (lc_all, "CHS ");

Why must I call setlocale?
In the C/C ++ language standard, the runtime Character Set environment is defined as "C", that is, a subset of the ASCII character set, when working, mbstowcs regards the string contained in CSTR as an ASCII character instead of a string containing CHS encoding, therefore, he splits each Chinese character into two ASCII codes for conversion. As a result, a string consisting of four wchar_t characters is formed. How can he make the mbstowcs work properly? You must explicitly tell mbstowcs that the current CSTR string contains a CHS encoded string by calling the mbstowcs command for conversion. You can use setlocale (lc_all,
"CHS") function calls are completed. Note that this function will change the character set encoding method of the entire application. You must call setlocale (lc_all, "C") again ") function to restore the string. This ensures that the string in the CSTR is considered as a Chinese string and converted into two wchar_t characters instead of four.

 

The localization settings must meet three requirements:

A. Language code B. Country Code)
C. Encoding (encoding)

Local names can be constructed using the following parts: language code _ country code. Code such as (zh_CN.UTF-8, en_us, etc)

For the alias table of locale, see/usr/lib/X11/locale. Alias (Debian GNU/Linux is used as an example)
