Thanks. On further investigation, I was reminded that stixsans (or
anything not in the BMP) doesn't work with Type 42 fonts. The way the
PDF spec forces you to deal with them, if it's even possible, is really
hairy. So to solve your problem you can either a) not use stixsans, or
b) use Type 3 fonts. We should document this somewhere.
In any case, we should still fix the crash bug on narrow (e.g. Windows)
Python builds, so the behavior of "no characters printed" is at least
the same on all environments. We should probably add some Type 3 vs.
Type 42 font regression tests as well.
