I've built a URL decoding option into the newest version of my discogs script.
[WS] Discogs (pone mod)
It works, but it makes the script slower.
I've only built in the first character set, called "Basic Latin", as I found it here http://www.utf8-zeichentabelle.de/unicode-....pl?number=1024 into my script.
That alone where 921 replaces. So if I wanted to build in all characters, that would really blow up the size of the script too much.
It should be possible to reverse decoding to encoding and write the syntax for export scripts.
Something like $replace(...,%21,!,%22,",%23,#,%24,$,%25,%,%26,&,...)
Keep in mind that you have to replace the special characters of the Mp3tag export syntax.
And you have to use a text editior where you can write all the special characters.
@Detlev:
Is there a way to built your tool into Mp3tag's Web Sources process?
