[Lohit-devel-list] Kannada GPOS issue

[shankar prasad]

Actually no Kannada fonts can handle a case like this in which a cluster of
four consonant (0ccd) and three halanths are there! The word you have
mentioned is a transliterated word from English. So in order to get good
readability, it is better to use a zero-width non joiner (u0ccd) after the
second consonant.

Also, in comparison with Gubbi and Navilu, Lohit doesn't handle the cluster
that good. This has been already reported by Shriramana Sharma:
https://bugzilla.redhat.com/show_bug.cgi?id=825081

By the way, in the image attached, you have added a space after the second
0ccd!
