问题 What is the difference between WideCharToMultiByte() and wcstombs() When to use which one? 回答1: In a nutshell: the WideCharToMultiByte function exposes the encodings/code pages used for the conversion in the parameter list, while wcstombs does not. This is a major PITA, as the standard does not define what encoding is to be used to produce the wchar_t , while you as a developer certainly need to know what encoding you are converting to/from. Apart from that, WideCharToMultiByte is of course a

问题 wchar_t is defined in wchar.h Currently, if the developers want to use only wchar_t , they can not do this without getting type conversion warnings from the compiler. If wchar_t will be made the same type as wint_t , it will be good for both parties. The developers who want to have both wint_t and wchar_t in their programs (for example if they want their code to be compiled not only under glibc) can do this without getting compiler warnings. The developers who want to use only wchar_t (to
