-- TODO
-- 1. [HACK] Aspirate aspirables
-- 2. Vowels with fixed characters (ā, ạ̄, ū, o, ō, e, ē, ọ, ọ̄)
-- 3. Initial variants of vowels (with alef)
-- 4. Medial variants of vowels (diacritics or standalone)
-- 5. Final variants of vowels (same as medial except: e, ē)
-- 6. Treat final yē and vāv differently depending on what comes before
-- 7. Treat final hē with vowel diacritic
-- 8. Fixed consonants and provided vowels
-- 9. [DONE] Disregard hat for nūn
-- 10. [DONE] Work around hat for rē
-- 11. [DONE] yē with hat is a palatal 
-- 12. [DONE] Kashmiri yē medial is 'a; final '
-- 12b. Check support for compound words
-- 13. Add vowels to consonants
-- 14. Add vowels to dual role characters

-- How to add vowels
-- Make list of consonants and vowels
-- Check if conditions are met (C+V; alef initial+V; vowel carrier + V)
-- Change
