I am often faced with this problem.
 
I have a string like (this was the "From" address of an email I recently received):
 
    =?utf-8?B?UGhpbGxpcCBHw7xudGVy?= <s69pguen@uni-bonn.de>
 
Note that this may not be the ideal example, but it is the one closest to
hand.  Here's another example:
 
    TF-8?q?Theyre_telling_us_something_about_something_ok?
 
when it should have been just:
 
    They're telling us something about something ok?
 
My question is: Is there a (Unix/Linux) tool that will reliably fix this?
I.e. convert the binary glop format into the desired, pure ASCII, format.

What you are looking at is the "punycode"[1] expression of a non-ASCII character
sequence.

Yup.  I've never heard the term "punycode" before, but it sounds appropriate.

AFAIK, there aren't any /standard/ utilities that convert to and from punycode.
However, there are /libraries/ that handle punycode (libidn[2], for one).

"standard" doesn't really matter much to me.  If there is a tool out there,
in any form, from any source, I'd like to hear about it.

Generally, when there is a library to do something, there is a program
written to access the functionality in that library - i.e., a "thin
wrapper" around the library.  Sounds like that program is what I am looking
for.

Kenny, I'll ask you to stop using quotes of mine as taglines.
