groff problems


It is reported by a few people that Debian's groff cannot handle 
some non-Latin1/Japanese languages such as Russian, Polish, and

# Bug#71744 for Russian and Bug#66928 for Polish are reported.
# http://lists.debian.org/debian-i18n-0007-msg00023.html is a
# report by Peter Novodvorsky.

This is due to Japanese patch, which reads continuing two >0x80
characters as one EUC (nearly equal to multibyte) character.  Thus,
two continuing Polish 8-bit characters cannot be displayed.  Since
all Cyrillic alphabets in Russian KOI8-R encoding are >0x80, only
the last character of words containing odd number of characters is
displayed.  Though I don't confirm Korean problem, I hope someone
will follow.

Some members including me (and a FreeBSD person) have discussed
about this problem personally.  Hereafter I would like to discuss
here.  (Discussions were started at a few places independently.
We should unite these discussions.  And more, we can read the
discussion via web.)

I think that the original design of groff is very confused and
wrongly localized to Latin-1.  Thus, to solve this problem,
we need radical re-designing and re-implementation of groff.
However, we need to fix the bugs ASAP.  And more, an ad-hoc
fix is already suggested.  Thus, I would like to discuss this
problem in two ways; one is about the 'ideal implementation',
and the another is about 'ad-hoc fix'.  Thus I will write two
follow messages against this message.
