I'm surfacing an issue from firstname.lastname@example.org because it may have
Currently, it's the rule that variation selector characters can't be
applied to combining characters. This is sensible in the case of true
diacritical marks: if two marks differ in shape, they ought in general
to be encoded separately, since marks are primarily shape-based rather
than functional in the first place.
It's not so clear, however, that this rule is appropriate when applied
to vowel signs. If some textual traditions represent vowels a and a'
differently whereas others unify them, and if the variation is not
predictable at the Unicode level, then it would seem appropriate to
provide a vowel sign for a and define a VSS <a, VS1> to represent a'
in those textual traditions in which it is in use. The alternative of
providing a distinct vowel sign a' and treating the difference as one of
spelling impacts backward compatibility and burdens textual processes.
