MultiByteToWideChar
The MultiByteToWideChar function maps a character string to a wide-character (Unicode) string. The character string mapped by this function is not necessarily from a multibyte character set.
int MultiByteToWideChar(
UINT CodePage, // code page
DWORD dwFlags, // character-type options
LPCSTR lpMultiByteStr, // address of string to map
int cchMultiByte, // number of bytes in string
LPWSTR lpWideCharStr, // address of wide-character buffer
int cchWideChar // size of buffer
);
Parameters
CodePage
Specifies the code page to be used to perform the conversion. This parameter can be given the value of any code page that is installed or available in the system. You can also specify one of the following values: Value Meaning
CP_ACP ANSI code page
CP_MACCP Macintosh code page
CP_OEMCP OEM code page
CP_SYMBOL Symbol code page (42)
CP_THREAD_ACP The current thread's ANSI code page
CP_UTF7 Translate using UTF-7
CP_UTF8 Translate using UTF-8
dwFlags
A set of bit flags that indicate whether to translate to precomposed or composite wide characters (if a composite form exists), whether to use glyph characters in place of control characters, and how to deal with invalid characters. You can specify a combination of the following flag constants: Value Meaning
MB_PRECOMPOSED Always use precomposed characters — that is, characters in which a base character and a nonspacing character have a single character value. This is the default translation option. Cannot be used with MB_COMPOSITE.
MB_COMPOSITE Always use composite characters — that is, characters in which a base character and a nonspacing character have different character values. Cannot be used with MB_PRECOMPOSED.
MB_ERR_INVALID_CHARS If the function encounters an invalid input character, it fails and GetLastError returns ERROR_NO_UNICODE_TRANSLATION.
MB_USEGLYPHCHARS Use glyph characters instead of control characters.
A composite character consists of a base character and a nonspacing character, each having different character values. A precomposed character has a single character value for a base/non-spacing character combination. In the character è, the e is the base character and the accent grave mark is the nonspacing character.
