I think this is happening because of a bug in the current beta of the  
Charis SIL fonts: what's happening is that the Regular font reports  
itself, in certain ways, as being italic; which then means that XeTeX  
doesn't find a separate "more italic" face to go with it; and then  
LaTeX attempts to fall back to slanted instead. Or something along  
those lines. Oh, and it fools fontspec's \emph code, I expect.

Ironically, it probably used to work OK because XeTeX was sloppier  
about finding styled fonts -- now that it is more careful, the bug in  
Charis is causing it to fail!

This should be fixed in the next Charis release, coming soon....

(Meanwhile, if you try \setromanfont{Gentium} instead, you should see  
italics where you expect them.)

I've fixed one issue in the code for 0.991, at least; I'm not  
completely sure if this is the only problem, but it seems to be  
working for me. I hope to find time to finish and release 0.991  
fairly soon, but email me if you'd like to hand-install and try an  
interim version to see if it solves the Greek issue for you.
