Well..... yes, it has crossed my mind. But I'm not keen on "typographic
chance"; I like to know what I'm getting. If the font I've asked for
doesn't have the character I'm trying to print, a square box that
sticks out like a sore thumb makes it fairly obvious that I need to fix
things. Silent substitution of another font may escape my notice until
the printer has run off a few thousand (or more) copies that don't look
Substitution with a warning message would be safer, but more work to
implement (for silent substitution, I could simply use
ATSUSetTransientFontMatching). Better still would be substitution with
a warning message, plus the ability to specify an ordered list of
fallback fonts to try.
I'll bear it in mind; meanwhile, comments from others would be welcome.
