Khmer: correction to Sign Coeng regex classification. #127

Closed adrianwong closed 3 years ago

adrianwong commented 3 years ago

U+17D2 KHMER SIGN COENG has the shaping class INVISIBLE_STACKER, not COENG.

adrianwong commented 3 years ago

Alternatively, we could imitate the regex for _ra_ and say

_coeng_     = The sign "Coeng"

or something to that effect?

The intent was likely to mimic the _ra_ approach, but in this case I think I like the INVISIBLE_STACKER better, since it preserves that property in reader-accessible form. Doesn't make a difference, number-wise, since there's only one either way, but it's more cautious, which seems to be wise considering the complexity of Khmer and the potential for more changes coming.
