Common encoding and decoding scripts

Common encoding and decoding scripts

We usually encounter various encodings. Here, I have summarized some common encodings, which are not very complete.

I tried to make a summary of encoding and decoding, and wrote a script. As python is not very good, it may not be possible. I hope you can correct me a lot.
