还是和之前的原因一个样，一直在用的 MD5 编码，处理英文时没问题，加了中文，就跟 https://tool.oschina.net/encrypt?type=2 和 https://md5jiami.51240.com/ 的结果不一样了，想了下，应该还是 UTF-8 编码的问题，于是将原来在用的编码中和字符串转 Byte 数组函数改装了一下，就成了，转换结果一致，说明工作正确：

其中改造了的函数就是 converttowordarray ，这个是将输入的字符串进行处理转换的。
使用例子如下：
msgbox md5("123中文，？αabc") '正确结果应为：2EC80A3192DB1122A1ED5884788C4027PS：之前，想用 Adodb.Stream 进行 UTF-8 编码转换，但是最后发现 VBS 在内存变量里面的字符串，永远是 unicode 格式，所以，.ReadText 后得到的字符串其实是无效的，改天试试 .Read 。
此记！
