No idea - I am not at all expert in coding systems or the internals of
Gnus.

This was the simplest patch that appeared to work for producing the
right display, without changing the decode into the " *mm*" prefixed
temp buffers created by the MIME machinery for each part.

If you think `decode-coding-string' is a better patch, feel free to test
and commit that instead.
