Assuming you're using fontspec.sty, try:

     \setromanfont[ItalicFont=Charis SIL Italic]{Charis SIL}

or something along those lines, if XeTeX is failing to find the  
italic face by itself. (Similarly for bold.) It seems to have trouble  
associating some font families properly; this is a known issue that  
I'd like to solve, if I can figure out the root cause sometime.
