I haven't played much with fonts before, so I'm afraid I don't know how
to do this.  I've played around with buffer-setting font code for half
an hour, and I'm still not able to get to a font object from text in a

So, starting with (say)

  (buffer-face-set '(:family "Symbola" :height 150 :width semi-condensed))
  (insert "This is a text"))

how do I get the font object for each character there so that I can feed
it to `font-get-glyphs'?

`buffer-face-set' is probably the wrong thing here, though, since we
would have many fonts in a buffer, but it's a start, perhaps...
