Basically, I don't object.  However, this solution doesn't scale IMHO.
Symbol fonts with a (3,0) can contain arbitrary glyphs that are mapped
to 0xF000-0xF0FF – it's not standardized in general.  In other words,
we can provide proper tables for `wingding', but this solution won't
work for other symbol fonts.
