ja_JP.eucJP locale is fixed by src/rxvt.h r1.265.
But ja_JP.UTF-8 locale is still weird.

Do you plan to merge doc/solaris9.patch?
It is based on Markus Kuhn's wcwidth.c[1],
but its ambiguous table is old (Unicode 4.0).
It has to be updated by Markus Kuhn's uniset Perl script[2].
It works well for ja_JP.UTF-8 locale.

I think -cjk_width option switch (like xterm) is
better than replacing wcwidth (src/solaris9.patch).
