UTF-8转GB2312:

char* convertUTF8ToGB2312(const char* utf8)
{int len = MultiByteToWideChar(CP_UTF8, 0, utf8, -1, NULL, 0);wchar_t* wstr = new wchar_t[len+1];memset(wstr, 0, len+1);MultiByteToWideChar(CP_UTF8, 0, utf8, -1, wstr, len);len = WideCharToMultiByte(CP_ACP, 0, wstr, -1, NULL, 0, NULL, NULL);char* str = new char[len+1];memset(str, 0, len+1);WideCharToMultiByte(CP_ACP, 0, wstr, -1, str, len, NULL, NULL);if(wstr) delete[] wstr;return str;
}

GB2312转UTF-8:

char* convertGB2312ToUTF8(const char* gb2312)
{int len = MultiByteToWideChar(CP_ACP, 0, gb2312, -1, NULL, 0);wchar_t* wstr = new wchar_t[len+1];memset(wstr, 0, len+1);MultiByteToWideChar(CP_ACP, 0, gb2312, -1, wstr, len);len = WideCharToMultiByte(CP_UTF8, 0, wstr, -1, NULL, 0, NULL, NULL);char* str = new char[len+1];memset(str, 0, len+1);WideCharToMultiByte(CP_UTF8, 0, wstr, -1, str, len, NULL, NULL);if(wstr) delete[] wstr;return str;
}
