Hmm.  cpphs doesn't do anything special with character encodings, so I
would guess this is a Hugs issue maybe?

I'm afraid our work firewall blocks all outgoing traffic to port 70, so
I can't download MissingH to try to reproduce the error.

Also, as you noticed, cpphs-0.7 is kind of old now.

Is there a more accessible mirror of MissingH anywhere?

I tried this with hugs-Sept2006 and could not reproduce the error.
Mystified.
