Feature request: ccmp substitutions for unencoded letters with overstruck tilde.

[jmcwilliams403]

According to L2/23-262, there exist more attested letters with overstruck tilde which were subsequently rejected by the Unicode consortium in favor of undeprecating Combining Tilde Overlay (◌̴) because of its continued/active usage in modern official IPA. Therefore, no more letters with overstruck tilde will be encoded as atomic characters in the future. However, visuals with their intended anchor points are shown in the aforementioned document:


By the way, at some point afterwards, Latin beta/theta/chi were unified with Greek beta/theta/chi for IPA usage (basically using an IPA font if there is a preference) so therefore "Latin Small Letter {Beta|Theta|Chi} with Middle Tilde" in the above images should function for both Latin and Greek, and also continue to work under IPA localization ('IPPH ')

May not need a real combination, could be impelemnted as a contextual subst.

Whichever way you want to approach this would work.
