China DOS Union

I have a text file where, for some reason, the decoding was incomplete, so many symbols were not decoded.
I need to replace them manually:

%2A replace with *
%40 replace with @
%2B replace with+
%2C replace with,
In short, all those HTML special character encodings need to be replaced with their corresponding symbols.
There are a whole series of replacements like this, which is very cumbersome.
I came to your forum because of its reputation, hoping to find a solution. Please give me some help, and thanks in advance.

Keyword: ASCII

I suggest using some third-party software to handle it.

Can you help me solve this problem? Or give me a piece of code

bat can't do it; if encoding is supported, the simplest way is to use vbs.

Could you provide a sample text, that is, a snippet from your text?

If you use the text replacement tool fr,

fr test.txt -fic:"%%2A" -t:"*"
fr test.txt -fic:"%%40" -t:"@"
.......

How many lines would have to be written like this =。= There are usually 86 characters...

If you use vim, you can use the following to get it done:

:%s/%\(\x\{2}\)/\=nr2char("0x".submatch(1))/g

Powerful vim replacement.

-_- My skills are limited,,,, that's the only way I know
If there were a list matching encoded characters to their equivalents, that would be a bit better

Thanks, brother. With the software you provided, I achieved my goal. Many thanks!
