Note that this is not the latest xetex code.....

You're running a version of xetex where bookmarks (and anything  
relying on \special, etc) will not fully support Unicode; I think it  
works OK for you in this example because the characters are limited  
to Latin-1, but it would fail with Chinese or Arabic or Hindi etc.

The latest xetex code (not sure if this is in the current Mac  
release, or only the pre-release sources) includes more complete  
Unicode support in this area, but a side-effect may be that it works  
*worse* in combination with something like [unicode]{hyperref},  
because of the conflicting attempts to process Unicode encoding forms!
