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...

not, 
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

പുറകോട്p

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

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
