Is the provisional property 'Indic_Syllabic_Category' defined by anything deeper than the UCD file IndicSyllabicCategory itself? I started to review the current assignments and realised I couldn't explain the division between Vowel_Independent and Consonant. Is the division meant to be rational or, although possibly consistent within a script, is it arbitrary?
For example, why are U+17A2 KHMER LETTER QA and U+0E24 THAI CHARACTER RU of category Consonant, while U+1021 MYANMAR LETTER A and U+1A50 TAI THAM LETTER UU are of category Vowel_Independent? Is this difference intended to matter? Both U+17A2 and U+1021 combine freely with dependent vowels, while U+0E24 and U+1A50 combine with very few dependent vowels (I think just U+0E45 THAI CHARACTER LAKKHANGYAO and U+1A63 TAI THAM VOWEL SIGN AA respectively). Another puzzle is that U+1038 MYANMAR SIGN VISARGA of category Visarga while U+19B0 NEW TAI LUE VOWEL SIGN VOWEL SHORTENER is of category Vowel_Dependent. Both may follow a final consonant (one of category Consonant_Final in the case of Tai Lue!) without implying a new syllable. Is the property meant to be tailorable? For example, there are encoded characters in the Khmer script that serve as tone marks when it is used to write Thai.
