One other point regarding usage: it would normally be simpler and  
more efficient to specify features such as the tex-text mapping when  
initially loading the font, either using

   \setromanfont[Mapping=tex-text]{...desired font name....}

or by using

   \defaultfontfeatures{Mapping=tex-text}

before the \setromanfont command.
