  This sounds odd.  I don't have them on my MacBook running Tiger, but I
can't help noticing that in Hoefler, the right double quote looks quite
closely like two apostrophes, so that when you input '' you get very
similar results with or without the so-called “smart quotes” (the
opening quotes don't look similar, though).  Anyway you shouldn't rely
on that feature being set automatically, see below:

  Just add the [Mapping=tex-text] option to fontspec, as Will said:

	\usepackage[Mapping=tex-text]{fontspec}
