[Fontconfig] how to recognize a fallback character

[Werner LEMBERG]

Folks,


we have a problem within lilypond.  This is probably a pango question
also, but let's start here :-)

Is there a way for fontconfig to signal that it has found a fallback
font instead of the requested one?  Or to say it differently: How can
an application find out whether fontconfig returns an exact match, a
user-defined alias (counting probably as an exact match), a good
match, and bad match, and no match at all?
