  You can use \font\myfont="Lucida Grande:mapping=tex-text"

  While this would be a waste of time for already existing documents, I
think it is advisable to do so for future files (I mean, keying in the
actual Unicode quotes by whatever mean when you type a new document).
After all, this is the whole point of Unicode.
