Indeed – left over from an earlier experiment.

Because of the '(#x10A3F . #x10A3F) bit? Yes, that may be a
problem. With Kharosthi Unicode, out of the following three
examples, the middle one (consonant + modifier + vowel) has its
vowel attached incorrectly
𐨗𐨸𐨁 𐨣𐨸𐨁 𐨐𐨿𐨮𐨸𐨁
Cf. 𐨣𐨸𐨁 with modifier with 𐨣𐨁 without modifier:
All look fine with Segoe UI Historic, however.
Can you suggest how to reformulate the rule? My intent was to pass
every whole akṣara to the shaper.
>> ("a" ["𐨀"]) ("i" ["𐨀𐨁"]) ("u" ["𐨀𐨂"]) ("R" ["𐨀𐨃"]) ("e" ["𐨀𐨅"]) ("o" ["𐨀𐨆"])

Okay, done. Please find new versions of both files attached.

I was dreading that process, but am willing. Yes, please send me
the forms.
Many thanks for your quick response and help!
