IIRC there was a problem like this a while back with a language like Korean or Taiwanese. You should browse here bugtracker
. If you find one that resembles what you are seeing then you can post to that ticket or if not create a new one. You will need to setup an account there as it is on a different system.
It would also help if you can post the ticket number here so other can see the progress, add information, or see the final results.
