It would have to be implemented.  The problem is that the PDF format 
uses UTF-16 internally for the bookmarks, so using curly quotes here is 
quite difficult.  Hence we are stuck with ASCII in the bookmarks.  I 
guess that " is better than `` but this may also be difficult to 
implement.  `` is a ligature in the fonts used that is a curvy double 
quote but the PDF bookmarks are completely separate - you'd need to 
change the two tokens `` to something else somehow.

I think I've fixed this problem in commit 4f92cb1.
