Urdu font problem

I have just started using ubuntu 12,04, there i have a problem with libreoffice. it does not show some of the characters of the urdu langage, instead boxex appear. what should i do?

Make sure you have fonts installed that cover these characters, and select one of the fonts for document formatting.

Right – as @cloph said, you’ll need appropriate fonts installed.
