Same issue on OS X  - with Gecko 1.9.0 ~ Gecko 2.0b.
(Safari doesn't show the issue, though).

This seems like reasonable behavior to me; if the page has U+0093 and U+0094 in its text, and there's no font available that supports those characters (which is hardly surprising, as they're obscure control codes), showing hexboxes is our expected response.

From looking at the page, I believe this is an encoding error, and they intended to have “quotation marks” there.
