I recently implemented UTF-7 encoding/decoding. It is distributed with
recent nnimap distributions
("http://www.extundo.com/nnimap/nnimap.tar.gz").

Code to interface with gnus is obviously not there.

I did the shortcut of assuming a latin-1 environment, but it should
be easy to extend to Unicode once that becomes available in Emacs.
