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.

Indeed, there is an "idn" tool as part of the libidn source.  The binary
is in a separate package from the library on Debian.  Perhaps that tool
will do what you want in the shell.

I don't know how it might be packaged for non-Debian distributions or
non-Linux OSes.  Maybe with the library, maybe not.

(BTW, I too have looked for such a tool in the past and come up empty.
The previous poster's mention of "punycode" and "libidn" were super
helpful to me, too.  Thanks Lew!)
