I know, this question has been raised several times on this list. But
I'm bad at searching, so I'm just asking:
How can I detect, whether a font contains a certain character (let's say
u2103=Degree Celsius symbol) from within XeTeX?
If a font has this glyph, I would like siunitx to use it as the unit
symbol for \celsius.
If a font doesn't have this glyph, I would like siunitx to use °C as the
unit symbol for \celsius.
