VC GBK与UTF8字符串的转换

可以用以下函数代码。其原理是先用“MultiByteToWideChar”函数把字符串转成unicode字符串，然后再用“WideCharToMultiByte”由unicode转成所需目的编码的字符串。

void ConvertGBKToUtf8(CString& strGBK) {    int len=MultiByteToWideChar(CP_ACP, 0, (LPCTSTR)strGBK, -1, NULL,0);    unsigned short * wszUtf8 = new unsigned short[len+1];    memset(wszUtf8, 0, len * 2 + 2);    MultiByteToWideChar(CP_ACP, 0, (LPCTSTR)strGBK, -1, wszUtf8, len);     len = WideCharToMultiByte(CP_UTF8, 0, wszUtf8, -1, NULL, 0, NULL, NULL);     char *szUtf8=new char[len + 1];    memset(szUtf8, 0, len + 1);    WideCharToMultiByte (CP_UTF8, 0, wszUtf8, -1, szUtf8, len, NULL,NULL);     strGBK = szUtf8;    delete[] szUtf8;    delete[] wszUtf8;} void ConvertUtf8ToGBK(CString& strUtf8) {    int len=MultiByteToWideChar(CP_UTF8, 0, (LPCTSTR)strUtf8, -1, NULL,0);    unsigned short * wszGBK = new unsigned short[len+1];    memset(wszGBK, 0, len * 2 + 2);    MultiByteToWideChar(CP_UTF8, 0, (LPCTSTR)strUtf8, -1, wszGBK, len);     len = WideCharToMultiByte(CP_ACP, 0, wszGBK, -1, NULL, 0, NULL, NULL);     char *szGBK=new char[len + 1];    memset(szGBK, 0, len + 1);    WideCharToMultiByte (CP_ACP, 0, wszGBK, -1, szGBK, len, NULL,NULL);     strUtf8 = szGBK;    delete[] szGBK;    delete[] wszGBK;}
