wide character (unicode) and multi-byte character
Wide character and multi-byte character are two popular encoding schemes on Windows. And wide character is using unicode encoding scheme. But each time I feel confused when talking with another team -- codepage -- at the same time.
I am more confused when I saw sometimes we need codepage parameter for wide character conversion, and sometimes we do not need for conversion. Here are two examples,
code page is used in WideCharToMultiByte when dealing with unciode character
code page is not used in wcstombs when dealing with unciode character
int WideCharToMultiByte (
LPBOOL lpUsedDefaultChar );
My question is, what is codepage (seems my current understanding is not correct)? Does codepage have anything to do with multi-byte character or only have relationship with wide character? Could anyone explain the meaning and relationship between codepage, wide character and multi-byte character?
size_t wcstombs (
const wchar_t* wcstr,
size_t count );
thanks in advance,
