FYI, We have japanese-hankaku[-region] and japanese-zenkaku[-region]
functions, which convert hankaku (halfwidth) and zenkaku (fullwidth)
characters to one another.  It is useful to normalize mixed text
mainly input by someone not me, though these functions don't support
all characters because they are for traditional Japanese character
set.
