Yes, that's understandable. My personal approach would probably be to  
redefine \L (in my preamble), if that's what LyX is generating, and  
add the font family switch to that. But use whatever solution works  
most conveniently for you!

There is a bug in xetex 0.996 (and earlier) that messes up infinite  
glue in right-to-left text, and this could well be affecting things  
like list item labels (which are often set in boxes of a fixed width,  
using infinite glue to deal with the alignment).

This bug will be fixed in the next release; it is corrected in the  
current source code in Subversion (which will become 0.997 when  
released), and a source patch for 0.996 was just posted to the tex- 
live mailing list.

Mirroring of parentheses (etc) is not implemented in xetex 0.996, but  
will occur automatically with later releases (thanks to an updated  
version of the ICU libraries). So using the development version of  
0.997 should solve this, too.

For Windows users, I believe Akira regularly builds the latest  
development code and posts this on his W32TeX page; you might like to  
try this and see if it resolves both the enumerate spacing and  
parenthesis mirroring issues. See the XeTeX-DEV release near the end  
of the page:
