Sometime ago we discussed the difference between EM SPACE and EM QUAD. We
agreed that effectively there is none. Is there then a reason why EM QUAD
seems to be missing from the line boundary control category (p. 48, TUS 3.0)
while EM SPACE, EN QUAD and EN SPACE are
listed ?

Regarding the Indic dead-character formation category (p. 49 TUS 3.0),
should U+0E3A THAI CHARACTER PHINTHU be part of it, since it is apparently a
virama when pali is written in Thai ? This seems to be the only class 9
character (virama) found on p. 81 that is missing from p. 49. Any reason ?
