setlocale 收藏
setlocale:
函数原形为：char *setlocale( int category, const char *locale );
头文件：<locale.h>
所支持的操作系统为:ANSI, Win 95, Win NT
对于简体中文可以使用如下设置：setlocale( LC_ALL, "chs" );
为什么一定要调用setlocale呢？
因为在C/C++语言标准中定义了其运行时的字符集环境为"C"，也就是ASCII字符集的一个子集，那么mbstowcs在工作时会将cstr中所包含的字符串看作是ASCII编码的字符，而不认为是一个包含有chs编码的字符串，所以他会将每一个中文拆成2个ASCII编码进行转换，这样得到的结果就是会形成4个wchar_t的字符组成的串，那么如何才能够让mbstowcs正常工作呢？在调用mbstowcs进行转换之间必须明确的告诉mbstowcs目前cstr串中包含的是chs编码的字符串，通过setlocale( LC_ALL, "chs" )函数调用来完成，需要注意的是这个函数会改变整个应用程序的字符集编码方式，必须要通过重新调用setlocale( LC_ALL, "C" )函数来还原，这样就可以保证mbstowcs在转换时将cstr中的串看作是中文串，并且转换成为2个wchar_t字符，而不是4个。
本地化设置需要具备三个条件：
a. 语言代码 (Language Code)
b. 国家代码 (Country Code)
c. 编码(Encoding)
本地名字可以用下面这些部分来构造：
语言代码_国家代码.编码 比如（zh_CN.UTF-8, en_US等）
locale的别名表见 /usr/lib/X11/locale/locale.alias(以Debian GNU/Linux为例)
