http://www-ccs.ucsd.edu/c/lib_prin.html 首先,%ls和%s的区别很简单,%ls意味着将对应的参数会被当作基于宽字符的字符串(wide chraracter string )看待,而%s则意味着对应的参数会被当作普通字符串(multi-byte string)看待。 其次,不要因为上面一句话而错误的认为%s只用于printf,而%ls只用于wprintf 。实际上,(...
C语言原本是在英文环境中设计的,主要的字符集是7位的ASCII码,8位的byte(字节)是最常见的字符编码单位。但是国际化软件必须能够表示不同的字符,而这些字符数量庞大,无法使用一个字节编码。 C95标准化了两种表示大型字符集的方法:宽字符(wide character,该字符集内每个字符使用相同的位长)以及多字节字符(multibyte cha...

A "string literal" is a sequence of characters from the source character set enclosed in double quotation marks (" "). String literals are used to represent a sequence of characters, which taken together form a null-terminated string. You must always prefix wide-string literals with the letter...
