function UnicodeToChinese(inputstr: string): string;
var
    i: Integer;
    index: Integer;
    temp, top, last: string;

            Result := Result + last;
            Exit;
        end;
        top := Copy(inputstr, 1, index); // 取出 编码字符前的 非 unic 编码的字符，如数字
        temp := Copy(inputstr, index + 1, 6); // 取出编码，包括 u,如u4e3f
        Delete(temp, 1, 2);
        Delete(inputstr, 1, index + 6);
        Result := Result + top + WideChar(StrToInt("$" + temp));
