I'm inclined to close this matter. If Apple changes font encodings
between releases (it's not even the same glyphs that are .notdef'ed!) we
can't help it. Besides, as I pointed out before, TeX documents normally
have their fonts embedded, AFAIK. Fixing this would probably need some
digging through the encoding tables and adding OS version switches there
(though I'm not even sure if it's (easily) possible to have a
conditional compilation depending on the OS version...).
Speaking of upstream: how do we go about submitting the patches? If you
want, I guess it's best if you would submit the patches, as you have all
the relevant data (what was broken where, ...) and can answer any
questions that may arise. If not, I could submit them as well, of
course, but it would be a lot like "here you are, do with it what you
