Re: PfaEdit and Unicode questions

You need a TrueType font editor program; there should be a free
one available at least on a trial basis.  (If you can't find one
for the Mac, I know there's a free PC one, and TTF is TTF the world
'round, so that would work too.)  You may have to re-draw the glyphs
within the TrueType editor, they're stored as equations of curves
rather than as graphics (although maybe that's how PfaEdit works
and there's an export/import channel that will work between them -
I have never heard of PfaEdit).

Anyway, given a TTF editor, you can open up your favorite system
font and add the glyphs, then add mappings to the appropriate Unicode
code points.  The details of how to do this vary with the editor,
but the TTF format supports multiple mappings between code points and
glyphs, and one of them will be what the system uses in Unicode mode.

Oh, even variable-width fonts have a characteristic glyph width,
and different fonts tend to have very different ones; since the fonts
scale to any point size, the  internal units are somewhat arbitrary.
So you may have to scale the new glyphs to match.
