Thanks for the response and thanks for working hard to make this single PDF work with Preview like every single other publisher has managed to do for every single other PDF I have.

I think it's unfortunate you failed at this mission, though, honestly. The book itself is could easily become the seminal Ruby book (replacing the PickAxe??) and it seems a cruel injustice to see it marred on the Mac this way, where Ruby itself has found such a strong community.

_why's contributions alone merit an extra effort at compatibility from all of us, so what I'd like to do is ask you which specific standard Apple isn't supporting that would cause this one font to render incorrectly?

In return for you help, I'll personally file a bug with Apple as well as pass this around to some people and see if we can't get some attention on the issue.

Thanks again, Allen.
