1. abvs is failing because we're performing adjustRephPosition function, hence,
the components required for abvs are not in correct sequence. Since there is no
unicode for reph glyph, I'm unable to adjust it after the abvs has converted
those components to reph glyph, and if it is not readjusted, then it applies
itself to wrong consonant. I think GPOS will be responsible for its reposition.
2. I don't know why blws failed; as you can see in [^output.pdf] glyph 663 (हृ)
is correctly exported from 362 (ह) and 372 ( ृ ).
3. cjct failed on one glyph (द्ध्र्य) because there are two virama glyph
components (द्+ध्+र्य). I don't know why but whenever there are two
consecutive virama glyphs in a word ( ् ) the feature responsible won't work.
Otherwise cjct is working as expected.
4. same with psts; we're adjusting reph glyph that's why psts isn't able to
find correct sequence of glyphs to apply properly on glyphs 326,578,661 (र्की)
and 368, 326 307 (किं) needs GPOS.
5. rkrf is most likely failing because it's borrowing glyphs from vatu. But you
can see in [^rkrf.pdf] the output is what we desired (क्रब्रप्रह्र).
I'll submit test files for Gujarati tomorrow. Please use latest version of
Lohit-Gujarati
https://releases.pagure.org/lohit/lohit-gujarati-ttf-2.92.4.tar.gz.
