The [unicode] option is needed with pdfTeX, and that's
what my previous comments were about.
I've not actually used it with XeTeX, and it was with
UTF8 input for XeTeX where your examples were failing.

As Jonathan says, it adds an extra layer of interpretation
of byte-codes, where perhaps there are other methods
available that would conflict with this.

Yes; it always takes 2 compilations for changes to become apparent.
The Bookmarks are built from the .out file of the previous run.

With this example, and XeTeX on MacOSX
    This is XeTeXk, Version 3.141592-2.2-0.94 (Web2C 7.5.3)

I get the following error:

(/Users/rossmoor/texmf/tex/latex/hyperref/nameref.sty) (./bmarktest.out)
(./bmarktest.out)
! Undefined control sequence.
\HyPL at Labels ->0 << /P (\3
                           76\377) /S /D >>
l.9 \begin{document}

?
! Undefined control sequence.
\HyPL at Labels ->0 << /P (\376\3
                               77) /S /D >>
l.9 \begin{document}


But just pushing on, it finishes OK,
and the Bookmarks all look fine!

Without the [unicode] option, the Bookmarks still
look fine, and there is no such error as above.

So the [unicode] option seems to be redundant,
and just mildly (for me) destructive.

It's nice to get a solution that removes unnecessary coding,
rather than requiring more coding to get a fix.


Cheers,
