What kind of fallback? IOW, what did you intend to do if you find out
that the font configured by the user does NOT have a glyph for the
character in question?
I'm asking because some fallbacks don't need to know whether a
particular font can display a particular character. But I'm not sure
those fallbacks are appropriate for your use case.

I believe you want font-get-glyphs.
