But note that the notion of "fullwidth" (zenkaku) and "halfwidth" (hankaku)
in CJK character sets is different from what is called "fullwidth" and
"halfwidth" in Unicode.
I think for Japanese Katakana you should use the "fullwidth" (in CJK
character sets sense) and not the "halfwidth" (in all three senses).
There was a nice explanation of this by Asmus Freytag on the CD-ROM which
came with Unicode 3.0
