[XeTeX] Suddenly fonts are not found

[Jon Breitenbucher]

Is there a way to do this from within the file? I usually have

%!TEX TS-program = xelatex
%!TEX encoding = UTF-8 Unicode

at the start of my documents so I don't have to select the correct  
processor.

Should

%!TEX TS-program = xelatex -output-driver="xdvipdfmx -q -E"
%!TEX encoding = UTF-8 Unicode

work?

It seems to be some issue with fontspec. More digging will need to be  
done on my part but that doesn't explain why all these old documents  
compiled with XeLaTeX have a problem with the mathematical characters.  
I have only done the regular system updates, all fonts appear to be  
active when looking in FontBook, and I did a complete reinstall of the  
MacTeX package this morning to try and resolve the issue. Puzzling.
