将gbk字符串转换成utf-8，存储到注册表中后，再次从注册表读取转换成gbk，有问题！！！

    char *a = "新2新";

    printf("gbk:'%s'\n", a);
    int ii;
    for(ii = ; ii < strlen(a); ii++)
    {
        printf("0x%0x ", (BYTE)a[ii]);
    }
    printf("\n\n");

    char b[] = {};
    size_t tt;

    toUTF8(a, b, , &tt);

    printf("utf-8:'%s'\n", b);
    printf("tt:%d\n\n", tt);

    setRegeditConfig_STR(HKEY_CURRENT_USER, REG_SOFT_KEY, key_file_dlg_choose_logo, b, tt + );

    //int ii;
    for(ii = ; ii < tt; ii++)
    {
        printf("0x%0x ", (BYTE)b[ii]);
    }
    printf("\n\n");

    unsigned long readLen = MAX_PATH;
    char filePath[MAX_PATH] = {};
    if(getRegeditConfig_STR(HKEY_CURRENT_USER, REG_SOFT_KEY, key_file_dlg_choose_logo, filePath, &readLen))
    {
        printf("filePath:'%s'\n", filePath);
        printf("len-utf8:%d\n\n", readLen);

        int ii;
        for(ii = ; ii < readLen; ii++)
        {
            printf("0x%0x ", (BYTE)filePath[ii]);
        }
        printf("\n\n");

        char *p = utf8ToGBK(filePath, &tt);
        printf("filePath-gbk:'%s'\n", p);
        printf("len-gbk:%d\n", tt);

        {
            printf("0x%0x ", (BYTE)b[ii]);
