Yes. The fonts I recommend most are
  - for programs using fixed-width fonts:
    Markus Kuhn's ucs-fonts package
      http://www.cl.cam.ac.uk/~mgk25/ucs-fonts.html
  - for programs using proportional fonts:
    the GNU unifont from Roman Czyborra
      http://czyborra.com/unifont/
    the BitStream Cyberbit font
      ftp://ftp.netscape.com/pub/communicator/extras/fonts/windows/Cyberbit.ZIP

Using xlsfonts.

I don't recommend it - it doesn't mix well with printf. Better use
printf with the %lc and %ls directives.

Sure, because EUC-JP has at most 3 bytes per char.

Use the ja_JP.SJIS locale. You won't be able to display JIS X 0212
characters in this locale.
