--- Comment #5 from Parag pnemade@redhat.com --- Thanks pravins for your conclusion about Malayalam rendering issue in bug 977764.
I just used fc-validate and found all the three fonts supports "Satisfy the coverage for ml language". So, I don't see this bug is valid anymore but definitely we got some valuable information here.
