主要用到兩個Api:

WideCharToMultiByte
http://msdn.microsoft.com/en-us/library/ms776420.aspx
ANSI <--> Unicode <--> UTF8
MultiByteToWideChar

WideCharToMultiByte

ANSI <--> Unicode <--> UTF8
- /*程式碼如下*/
- Code Snippet
- wchar_t * ANSIToUnicode( constchar* str )
- {
- int textlen ;
- wchar_t * result;
- textlen = MultiByteToWideChar( CP_ACP, 0, str,-1, NULL,0 );
- result = (wchar_t *)malloc((textlen+1)*sizeof(wchar_t));
- memset(result,0,(textlen+1)*sizeof(wchar_t));
- MultiByteToWideChar(CP_ACP, 0,str,-1,(LPWSTR)result,textlen );
- return result;
- }
- char * UnicodeToANSI( constwchar_t *str )
- {
- char * result;
- int textlen;
- // wide char to multi char
- textlen = WideCharToMultiByte( CP_ACP, 0, str, -1, NULL, 0, NULL, NULL );
- result =(char *)malloc((textlen+1)*sizeof(char));
- memset( result, 0, sizeof(char) * ( textlen + 1 ) );
- WideCharToMultiByte( CP_ACP, 0, str, -1, result, textlen, NULL, NULL );
- return result;
- }
- wchar_t
- {
- int textlen ;
- wchar_t * result;
- textlen = MultiByteToWideChar( CP_UTF8, 0, str,-1, NULL,0 );
- result = (wchar_t *)malloc((textlen+1)*sizeof(wchar_t));
- memset(result,0,(textlen+1)*sizeof(wchar_t));
- MultiByteToWideChar(CP_UTF8, 0,str,-1,(LPWSTR)result,textlen );
- return result;
- }
- char * UnicodeToUTF8( constwchar_t *str )
- {
- char * result;
- int textlen;
- // wide char to multi char
- textlen = WideCharToMultiByte( CP_UTF8, 0, str, -1, NULL, 0, NULL, NULL );
- result =(char *)malloc((textlen+1)*sizeof(char));
- memset(result, 0, sizeof(char) * ( textlen + 1 ) );
- WideCharToMultiByte( CP_UTF8, 0, str, -1, result, textlen, NULL, NULL );
- return result;
- }
