I do agree as well. I have removed the mapping to റ + ് + zwj .

 As this is non-standard, it has to get removed . so the sfd file has been
modified to reflect the changes .

Now, we had kept a single glyph i.e. one to which unicode value & unicode
char  gas been assigned .

 The Lookups has been updated with the rules for proper formation of the
ligature .

Yes. This is the bit we are hanging in. yet not getting the solution for
this. Better if you have a look at link
http://www.unicode.org/L2/L2007/07393-mala-dot-reph.pdf (page 6)
{specifically v2, v3 & v3 sections } . Please let us know if you have any
solution. Will surely work in that direction.

Pravin Satpute & Shriramana Sharma had already answered about this.

Ani Peter had helped in design issues. Shriramana Sharma had explained the
thing about inclusion of dandas, very nicely.

Thank you once again for the feedback. I had reported & resolved all these
issues (except the one i.e. lllamlm_viramamlm.half_vamlm ) on github
https://github.com/pravins/lohit/issues?state=open. The changes are now
updated in lohit2. Those will be updated in lohit in next release as pravin
has said.

Thanks & Regards ,

Sneha Kore
