Thanks a lot for this and for the suggestion regarding font switching.

For the mirroring, I uploaded a LyX document (so people who have LyX
installed can see what the document should look like; just enable
right-to-left processing in LyX), the XeLaTeX output (with a trivially
modified hebrew.ldf for babel, which replaces the encoding from LHE to EU2),
and the PDF output from xelatex. Single english words are surrounded by
correct parentheses (I guess this is a result of grouping the LTR chars, not
mirroring) but longer phrases are not. I'm not even sure that LyX is
generating correct parentheses in RTL text.
