 Not sure whether you already know the source of the "f" problem and 
simplified the explanation, or whether you don't know where this 
comes from, but this looks to me like ligatures are turned on where 
they shouldn't. Ligatures are a typographical fanciness for 
representing certain character pairs with a single character that 
looks like an amalgamation of the two. Often done for fi, fl and a 
few others.

 I think there should be a way to turn of ligatures, but you may have 
to use the Cocoa text system directly instead of using NSString's 
drawAtPoint:.

 There's http://lists.apple.com where you can find the Cocoa-Dev mailing list.
