[Groff] CJK typography support?

[Zhang Weiwu]

Hi all.

First congratulations on putting UTF-8 encoding support into groff. I am
using the CVS checkout, at the moment no release version can read roff
script in UTF-8 yet.

Next would be push this internationalization effort a little bit more
for adding CJK typography support?

There are information can be looked up on the Internet. But generally a
very small trick of simply adding an  zero-width space before and after
each ideograph can make the print at least readable. Currently groff is
not usable for text with mostly Chinese ideograph, because each
paragraph only has one line, has no linebreak within (groff only
line-break where space is, a typical Chinese paragraph doesn't have a
single space in it). Once someone started to use it they can contribute
more ideas / code / know-how on how to make it better.

Best regards
