That seems reasonably obvious, and I don't know why I didn't
think of that. However, there's still a question here: if the 7
used for glottal stop is just a glyph variant of U+0294, then
why wouldn't we also consider the same to be true in the case
of the right singly curly quotation mark glyph used for glottal
stop? I.e. why is it that, on the one hand, we encode the
orthographic character that looks like ' and that typically
represents the phoneme glottal stop as a separate encoding
character using separate codepoint, U+02BC; but, on the other
hand, we treat the orthographic character that looks like 7 and
which typically represents the same phoneme as a glyph variant
of the IPA symbol for the phone glottal stop. There seems to be
some inconsistency here.
