There are some change on that front ongoing.  First of all now that 
we use perl, all the encodings known to perl are supported.  There are
also some progress on line breaking for east asian languages, you can 
have a look at

What we use in tp/ is Unicode::EastAsianWidth to determine whether
the character has a double wide, and at teh same time whether it is
possible to end the line right after it.

What do you mean with 'Japanese comma' or 'Japanese period'? Is it
an unicode character or a , or .?

That is not supported right now.  But my opinion is that it is more
a language support thing, that should be in perl or in a perl module,
used in tp, but not something we do only for texinfo.  Are there Unicode
classes for kinsoku characters?  Is the description on

I ran it through tp, but don't know what to look at to see if it is 
correct, not to mention that it do not display the correct characters
for me.  If you want to, you could have a try at tp and see if the result 
is correct, by doing a checkout of the cvs version of texinfo and doing

cd tp
cp ~/my_japanese_file.texi .
./texi2any.pl my_japanese_file.texi

and look at the result with an info reader.
