There is free font (GPL-2+) available at,
http://www.exnet.btinternet.co.uk/ori/OriFonts.zip (which is also
upstream of Utkal font). The zip contains,

* ori1UniBold.ttf
* ori1UniMed.ttf

fonts. Please check possibility to package them in -extra package.

The file is gone but archived in the web archive.
It seems the existing utkal.ttf is the same font as the requested
regular version except for the family name. Can you explain?
