When calling a font with fontspec use [Mapping=tex-text], or for all  
fonts use \defaultfontfeatures{Mapping=tex-text}.

In English (not my mother language) I could never find out if there's  
a difference between double and single quotes and if so what each type  
of quotes means. I thought maybe one type was used when quoting  
somebody and the other type for meaning so-to-say or so-called, but I  
could never find a logical pattern.

In French we always use guillemets « », though now with more and more  
people writing on computers you tend to see quotes " " more and more  
often.
