Yeah, but surely there must be some other program (other than Emacs)
that actually uses this syntax for specifying fonts? I thought it was
supposed to be... "the way"...

Huh.

Indeed, the Pango round trip through symbols is inherently breakable. I
mean, the Gtk chooser knows exactly what font I've selected -- but is
there any way to get it to cough up that instead of the Pango weights?
I've looked at the documentation
https://docs.gtk.org/Pango/struct.FontDescription.html
and nothing really jumped out at me. I mean, in this case, Pango
reports a weight of 330 for book... but the actual weight in the file is:
weight: 53(f)(s)
So after mapping to symbols and back again, we'll never find that font
(because "book" is at 80).
But... what does (f)(s) mean here?
