I assume this is a problem only with Meera font - is it reproducible with Rachana or any other font?
This might be the same issue of fontconf matrix...

this is happening due to Em- square issue of U+0D4D
see its right bearing is just 10, even though it required right bearing at 299
thats why next letter 'P' is merging with U+0D4D
why right bearing is kept so less?
I think it should be 299+ when U+0D4d will be last character.
same for U+0D02
I have tested this with Meera, Rachana and Lohit. For Meera, the cursor stands before 0D4D (്), Rachana in the middle and Lohit at the end. Screenshots attached

working sfd for Meera
was trying to investigate problem with pravi.a and naveen,
by adding dist feature we can resolve this problem, but need to check some exceptional condition as well
attaching .sfd with added dist feature in it, but not complete (and not working for all cases) need to update and test it for all cases
resolved this one!!
scratch build is available on http://koji.fedoraproject.org/koji/taskinfo?taskID=2353995
i have tested it from my side so it will not add any regression
please test this and let me know your view on same
modified source file is @ http://pravins.fedorapeople.org/Meera.sfd
binary file for testing @ http://pravins.fedorapeople.org/Meera.ttf
Naveen can you build this for devel?
