Python：如何过滤特殊字符和乱码的字符

Question

问题：有上万个文件，其中很多的文件名包含有特殊的字符（确切的说是乱码字符），想写个python脚本来过滤掉，只保留正常的文字（包括字母、数字和汉字）
首先想到的是使用正则来匹配，但是正则不是很懂，希望大神帮忙提示下，谢谢啦
乱码字符比如：

这只是我随便列举的，只要能过滤掉非正常的字符就行

Answer 1

None of the characters here are correct, it is a decoding problem. For example, it turned out to be ascii, but it turned out to be decoded using utf-8, or ISO-Latin-1, and it naturally became garbled.

Since you updated the question, I will also update the answer.

Write a loop, scan all the words aside, and then use hex(ord(VARIABLE)) to spell them together to see if they are within the range.

Of course, no matter how you do it, it will look stupid.
