[XeTeX] Degree symbol

[Hooman Javidnia]

Hello,

I need to typeset degrees symbol in a LaTeX document that I am setting
in XeLaTeX. I have set default font features as
\defaultfontfeatures{Scale=MatchLowercase, Mapping=tex-text}
When I use the Unicode degree symbol (on a Mac keyboard
Option-Shift-8, like 360°), I get an error message. Should I change
the Mapping of the fonts? Is there  a better way of doing this in
XeTeX? I know that I can use ^{\circ}, but it would be better not to
use math macros in this document.

Regards,
