I've seen this before, and IIRC it seems to be a ligature in the 
Hoefler AAT tables that for some reason can't be turned off. I'd 
consider it an Apple font bug. (If you have the Developer Tools 
installed, you can run WorldText and see the same thing happen there.)

You should be able to work around it by putting something before the 
slash that will break up the text run; e.g., a kern. So "o\kern0pt/" 
should render as "o/" without forming the ligature.
