As of this afternoon, the latest xdvipdfmx code in Subversion  
includes Unicode support for bookmarks (etc).... this is obviously  
prompted by Timothy's contribution, but implemented in a slightly  
different way.

With this implementation, the Unicode support is automatic; you  
should *not* include a pdf:tounicode special in the source document.  
(That is still supported, so that the driver could still be used with  
non-Unicode TeX systems and tounicode mappings, but it should not be  
needed for Unicode/xetex.)

Feedback is welcome; it seems to work in my small tests (even  
including bookmarks with supplementary-plane text, although not all  
viewers display them properly; Reader 7.0 does, though).
