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

");

    char b[1024] = {0};
    size_t tt;

    toUTF8(a, b, 1024, &tt);

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

", tt);

    setRegeditConfig_STR(HKEY_CURRENT_USER, REG_SOFT_KEY, key_file_dlg_choose_logo, b, tt + 1);

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

");


    unsigned long readLen = MAX_PATH;
    char filePath[MAX_PATH] = {0};
    if(getRegeditConfig_STR(HKEY_CURRENT_USER, REG_SOFT_KEY, key_file_dlg_choose_logo, filePath, &readLen))
    {
        printf("filePath:'%s'
", filePath);
        printf("len-utf8:%d

", readLen);

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

        char *p = utf8ToGBK(filePath, &tt);
