这段代码提供了两个函数，ConvertUtf8ToGBK和ConvertGBKToUtf8，用于实现UTF8字符串与GBK字符串之间的相互转换。函数内部使用了Windows API MultiByteToWideChar和WideCharToMultiByte进行编码转换。

    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;
    }

    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;
    }
