I don't think that's a Gnus issue, and maybe even not even an emacs
issue.

Could you try to reproduce the issue with emacs in some other terminal
emulator instead of the one you are currently using?

And what happens when you put the "odd" characters into some file and
find that from within emacs?  Also garbage?  And what if you cat the
file, or open it with less?

I think it looks like a problem with mintty.

Yes, exactly that.  You can do that when you open the article with gnus
and then do `O f ~/the-article.txt RET'.

And also you might want to test it without emacs using

  $ less the-article.txt

and

  $ cat the-article.txt

on the command line.  If the terminal emulator has strange display
issues afterwards, then it's its fault.

That's just some ASCII encoded version of what the email client should
actually display.

I'm really no expert with respect to encodings and how those have to be
displayed, and what might happen if the declared encoding doesn't match
the contents of the mail.

Probably, if that mail is not confidential, you should write a bug
report using M-x gnus-bug RET and attach the problematic mail.
