   see: http://launchpadlibrarian.net/45734891/LC_ALL_set___ja_JP.UTF-8.png

Supplementary info:
   If you set LC_ALL env variables, ubiquity will select valid font set.

    2) Type below in "Run Application"
    /bin/sh -c 'LC_ALL=ja_JP.UTF-8 ubiquity'
    3) You will see valid font sets.

Notes:
   Traditional/Simplified Chinese and Japanese have same Kanji characters, but
   they not use same variant, so fonts are not same.

   This confusing is something odd, like mistake Ä for A.
