KeePass on openSUSE 12.1 also suffers this problem.

Title:
  Mono renders non-latin characters as squares. Fonts substitution
  error.

Status in Banshee Music Player:
  New
Status in The Mono .NET development environment:
  New
Status in “mono” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: mono

  When an application is being run we expect to be able to see the non-latin characters like CJK ones.
  What happens is they're being shown as empty boxes|squares.

  My Ubuntu version is Maverick and i'm using the default mono and winforms packages:
  - libmono2.0-cil 2.6.7-3ubuntu1
  - libmono-winforms2.0-cil 2.6.7-3ubuntu1

  Afaik the problem is related to WinForms or to Ubuntu itself.
  Someone addressed this as an issue in thaifonts-scalable package. But as long as i'm not using that package and that issue is fixed for maverick, this is not the same bug. File /etc/fonts/conf.avail/89-ttf-thai-tlwg-synthetic.conf is not even present.

  How to reproduce the issue. Lanch a mono application, like KeePass2
  and type in the search box a CJK text or paste one like 我 (for
  chinese) or 私、わたし (for japanese). They're instantly shown as empty
  boxes.
