AFSIK it's not really a matter of whether the drivers can access all glyphs
or not, but rather a matter of which glyphs are included in the fonts. Mac
fonts are (quite logically in most circumstances) usually set up to match
Apple's extension of 7-bit ASCII, not Adobe's, so some glyphs in the Adobe
set might not be included. You can always set up a Quickdraw font that
allows you to access any sufficiently small (up to 224 characters is no
problem) subset of glyphs from a Postscript font through Quickdraw alone.
(Doing it by hand though is about as making a TFM+VF from an AFM without
using VPtoVF or fontinst.)
