Ah, I see. LyX actually does not use the unicode characters “ and ” but 
\textquotedblleft and \textquotedblright{} when I insert the unicode 
character. So, I guess what I want is to have `` and '' be replaced by 
those commands.

Yes, using xetex changes the code preview to usage of unicode. Is it on 
purpse one cannot useb pdflatex that way?

By the way, I noticed two strange things:

1. If I typeset the document I sent before first with pdflatex and then 
with xetex I get an error:

  \babel at aux{english}{}

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

If I typeset a second time with xetex or straight from the beginning, it 
works as expected.

2. With xetexThe plain quotation marks show as Mapping=34 in the bookmarks.
