USE overrides for cantillation marks U+1CF8 and U+1CF9 #24

Closed dscorbett closed 2 years ago

dscorbett commented 2 years ago

The cantillation marks U+1CF8 and U+1CF9 do not match any USE subclass and therefore form independent clusters, which was surely not what was intended. Their Indic_Positional_Category should be overridden to Top, which will make them match VOWEL_MOD_ABOVE.

Thank you! I've added overrides for these code points to ISC= Cantillation_Mark; and IPC = Top.
