OK.  And what about CHAR+FE0E when CHAR is not an Emoji?

Anyway, I think you should install the patch on emacs-29, and we
should then try to fix the text-representation bug with VS-15 on
master.  (I guess it requires a change to font.c or something?)

Depends on the solution, I guess.  Isn't it just a change to the
VS-16's entry in composition-function-table?  Or maybe a change in the
#x20e3's entry?  (Did we discus the Emoji_Keycap_Sequence case before?)
