Handa made a change to jka-compr in the emacs cvs (2003-01-24), adding
decode-coding-inserted-region which I believe is meant to do emacs'
usual charset guessing and priorities, like find-file.

I had meant to propose a patch (for gnus-mime-copy-part actually) to
make use of that, either by copying that code from the cvs, or just
using it if emacs is new enough to have it.  Unfortunately I never got
around to working out the details.

If there's a cookie in the file, can't emacs just use that, without
needing a mime charset parameter?

Maybe you can use jka-compr the same way that
gnus-mime-jka-compr-maybe-uncompress does.  Or that function becomes
gnus-mime-copy-part-jka-insert with a patch I'm proposing - see other
message.  That would have the advantage of letting the user customize
compression methods.
