	not sure, i guess there shoulde be japanized bash.
	for /bin/sh, if there's no setlocale() call, it will be C locale only.

	there are people using Japanese string for filenames.  also,
	think about it:
	$ grep 'sushi' /tmp/foo
	how do you put "sushi" in Japanese letters here?

	i vote for (3).  if you use mbrtowc() in shquote(), like printf() is
	using it,
	- if you are using C locale it works just like now
	- if you use some other locale setting, it wlil be supported
		but for /bin/sh, it won't be the case until we have setlocale()
		call in /bin/sh)
