I don't quite follow this. What do you mean by "initial font" here? Sorry
if I'm being slow!
I mean the parameters passed to rufl_paint and friends (i.e. the font
face the client asks for)
So, the substitution table is just a single mapping of UCS code point
->
one (of a possible many) fonts that contain a glyph for that code point?
That's what I wrote, yes.
Is the font chosen just the first one RUfl encounters
(alphabetically?)
that has a match?
Pretty much, yes. See:
http://source.netsurf-browser.org/trunk/rufl/src/rufl_init.c?revision=979...
And what does RUfl take as hints to the font style from the name?
".Medium" and ".Bold", that kind of thing?
Yes.
See:

Patches to improve the situation are always welcome.
