This might be the most suitable occasion to decode raw data into
the human readable ones rather than only converting the multibyteness.
It suggests there will also be such items lying about here and
there.  Though I think it should be done for the second step.

Great.  I agree with installing those two changes as the first
step, though it might force non-ASCII people to live hard with
No Gnus for a while,   I will one by one fix or at least report
things caused by it.
