dDa dSignVocalicR Glyph is not activate when previous Glyph is Half form of Devanagari (Hindi) character.

If I type सम्यग्दृष्टि, dDa dSignVocalicR is not activate, like this screenshot:

and if I type only दृष्टि, dDa dSignVocalicR is activate like this screenshot:

This is because the ग्द conjunct sequence is being rendered as a ligature, not with an actual half form glyph (I do this to be able to more precisely control ikar selection and contextual displacement of anusvara (and candrabindu in Nepali).

I will examine the lookup ordering and see if there is somewhere I can insert a contextual control to decompose to a half form rendering if the final consonant forms a ligature with a following vowel sign.

As long as I understand this is nothing related with 'ikar' or and 'anusvara', It is purely shows that when I use 'dDa dSignVocalicR' solely the glyph nameed 'dDa dSignVocalicR' visually/activate perfectly, but in every case where previous character before 'dDa dSignVocalicR' is in half form like if i will try to type dN+dDa dVocalicSignR' will also not activate glyph named 'dDa dSignVocalicR'.

in short if I use only 'dDa dSignVocalicR', that will activate glyph and visually look perfect like inbuilt font glyph.

If there is any half character before 'dDa dSignVocalicR' which already have conjunct glyph like 'dNDa' in font, in this case too the inbuilt glyph named 'dDa dSignVocalicR' is not activate,

but if any character/half character which is not have conjunct glyph with 'dDa', like if I want to try 'dK+dDa dSignVocalicR', it will activate 'dDa dSignVocalicR'.

So it's not about ikar or and ansvara, it's about bug in to activate glyph 'dDa dSignVocalicR'.

Yes, I understand.

I explained about the ikar and anusvara because they are the reason why the conjunct sequence is handled as a ligature and not composed from a sequence of half form plus full form glyphs. That ligature is preempting the Da+VocalicR ligature. I need to examine the lookup ordering to figure out the best way to fix this.
