There is a further issue. Is <consonant1, sign_e, virama, consonant2><br>
a correct Brahmi sequence for two syllables? I suspect this will be<br>
split up by HarfBuzz as <consonant1, sign_e> <U25CC_glyph, virama,<br>
consonant2>, as seems to happen with Tai Tham. I'm going by my Tai<br>
Tham font that doesn't attempt to correct the USE, Da Lekh Seri - I am<br>
very rushed at the moment. This would fall foul of the combination of<br>
virama with a consonant that needs to happen before Indic<br>
rearrangement. If the correct encoding is <consonant1, sign_e, virama,<br>
ZWNJ, consonant2>, then my simple hack should work well. <br>
<br>
