If blind copying of Lamphun or Da Lekh, which I allow and encourage in this respect, is not possible, then one can reduce the skill level in one ways. One is to indiscriminately eliminate dotted circles that follow marks; that would simplify the conditions in those fonts. (I know that eliminating dotted circles present in the original string is wrong - it's collateral damage in opposing oppression.) Unfortunately, it's not as simple as that. If the USE is still misclassifying the InSC medial consonants as USE-medial consonants, then they can still leave one with the need to do Indic reordering in the font, e.g. with the reflexes of <consonant>/ria/, to be encoded <consonant, MEDIAL RA, SAKOT, LOW YA, SIGN E>, as the dotted circles prevent SIGN E reordering to the start of the cluster. The second way is to attack individual cases. For example, one probably get away with a special substitutions to repair the HarfBuzz and Windows corruptions of ᨯᩪᩕᩣ. I don't know if CoreText has yet another corruption. Richard.
