But this is in the graphical display -- the user has no way of knowing
what they're entering (it's just the glyph, not the name).

The other interface (the text-based one) lists all glyphs, even the ones
that Emacs can't display, so that'd be the way to insert such emojis.

I've poked at the problem some more, and it seems like
`char-displayable-p' is really fast on characters it can actually
display, but slow on characters it doesn't know about?  Perhaps this
makes it trigger loading more fonts or something?  (I haven't actually
read the code yet, just done some testing.)  If this is the case, is
there a way to say "don't try to load anything, but just see if you have
the glyph in the current set"?

I don't think it's necessary, but if people request it, I don't object
to adding it.  (But I don't think anybody will.  🙃)
