Eli> OK. And what about CHAR+FE0E when CHAR is not an Emoji?
Then you get the (composed) text presentation (and the composed emoji
presentation when itʼs CHAR+FE0F).

It requires something that answers the question "what font would we
use for this codepoint if it was not an emoji?". Maybe we can have a
separate fontset that pretends that the emoji script is equivalent to
symbol? Or invent some kind of 'text-presentation-font' property to
put somewhere?

Eli> Depends on the solution, I guess. Isn't it just a change to the

Itʼs a change to the VS-16 entry. We did discuss it before, and
decided to put it aside because the solutions all involved adding
composition-function-table entries for 0-9 or similar. I donʼt
remember why we didnʼt consider adding to VS-16ʼs entry.
Iʼll do some more testing, and post a final version hopefully this
weekend sometime.
