#61 Latin letters glottal I/A/U: U+A7BA-U+A7BF

[Daniel Werning]

Egyptological community would be happy to see the following characters added:
U+A7BC LATIN CAPITAL LETTER GLOTTAL I
U+A7BD LATIN SMALL LETTER GLOTTAL I
= egyptological yod
Note that the 'glottal hook' is placed above the small letter, but before the capital letter,
cf. https://unicode.org/charts/PDF/UA720.pdf.

(Optionally, for Ugaritic purposes, it would be nice to also add analogous:)
U+A7BA LATIN CAPITAL LETTER GLOTTAL A
U+A7BB LATIN SMALL LETTER GLOTTAL A
U+A7BE LATIN CAPITAL LETTER GLOTTAL U
U+A7BF LATIN SMALL LETTER GLOTTAL U

This looks like a thing worth doing. My go-to sources for Unicode don't have a lot of data for these characters. Do you know if this "glottal hook" is in the standard as a combining mark? E.g. a variant form of 0133 "Combining comma above"?

[Daniel Werning]

I would prefer a (slightly smaller) version of the upper hook ꜣ U+A723 in your font.
Otherwise ʾ U+02BE or ͗ U+0357 might serve the purpose.

Thanks--this is a help.
