UTF-8 is 32-bit because it is a variant of UCS-4.
Though GNU libc-based system has 32-bit wchar_t, how about portability?

I found another problem that groff-1.16 never use hyphenation.
(I tried 'LANG=en_US man ls' using groff_1.16-0 and groff_1.15.3-1.
Of course I deleted /var/cache/man/cat1/ls.1.gz.)
