The fongman and phnek moan (U+0E4F THAI CHARACTER FONGMAN
and U+17D9 KHMER SIGN PHNAEK MUAN are related characters, but
some of their properties are different. In particular, the fongman has
a Line Break class of AL while the phnek moan has class NS. What little
I know about the phnek moan makes it seem peculiar that its Line Break
class is NS. Is there truly a distinction between how these two characters
are used in their respective scripts that makes this difference warranted,
or is this a possible error in the standard that deserves official scrutiny?
