[XeTeX] hyperref 6.79n breaks xetex's (xdvipdfmx) ability to set proper page dimensions (and overrides page dimensions on pdftex)

Yes that is what I meant. Because of this I would at first try
without the option.

I don't know but this one works fine:


But I have no idea which encoding is used in the bookmarks and if it
works with chars from other part of unicode too.

Well probably because a lot of people had problems with page size
when using the standard classes (like article) without geometry.

I think it does but at a different time. So now the other setting
wins. It is a bit of a problem: on the one side there are documents
which use a class like article and which doesn't set the
pdf-pagesize, on the side you have documents were the class,
geometry and hyperref (and sometimes user commands) compete to
declare (sometimes different) the page size.

Probably we will need in short time a FAQ "how to disable page size
setting in various packages" ;-).
