Detailed Description

Lohit Odia and Telugu fonts are available from 2004. Over the years number of redundant and incorrect open type rules got added into this to cope up with different layout engine available with Pango, Qt and ICU. We started using Harfbuzz-NG unified shaper in Fedora from Fedora 19. Its time to clean-up Odia and Telugu open type tables and make them effective and efficient by following all the standards around font technology. Under Lohit2 project this is happening during Fedora 22 development cycle.

Benefit to Fedora

Lohit Odia and Telugu are default fonts for Odia and Telugu language respectively in Fedora. Making these fonts as per latest open type specification and following recent language related guidelines further help to prove Fedora leadership in language technologies. Optimization in font happen w.r.t. Glyphs and open type tables.
