    It's the only Thai script sample for a Mon-Khmer language that I could find
    at the Rosetta Project today, though the blob seemed larger when I looked at
    the sample before.

    There's some pretty fancy contextual positioning going on there if it is
    PHINTHU. PHINTHU is normally positioned bottom right, but Kuy uses it as a
    vowel modifier and positions it mid bottom. The logic looks as though it is
    to centre if if the consonant is O ANG or if the consonant has a preposed
    vowel - SARA E is the only example I saw in the current Rosetta Project
    specimen. (Positioning it bottom right would do if it were modifying the
    implicit vowel in closed syllables, as I have seen proposed for one
    language's orthography.) The use as a vowel modifier seems to have been
    borrowed from U+0323 COMBINING DOT BELOW in its significance of 'IPA: closer
    variety of vowel'. Should the meaning 'closer variety of vowel' be added to
    'Pali virama' for U+0E3A THAI CHARACTER PHINTHU'?

    [It was on the (private) Unicore list - I've already pointed PC to the
    archive of the thread.]
