I'm afraid it doesn't work on my machine ;-(

Here is my file:

\documentclass[12pt]{article}
\usepackage{fontspec,xunicode}
\usepackage[dvipdfm,pdftitle={χαλεπὰ τὰ καλά}]{hyperref}
\setromanfont{GFS Didot}
\begin{document}

\emph{Beautiful is though.}

\end{document}

And I get the following message from xdvipdfmx

** WARNING ** Failed to convert input string to UTF16...

\AtBeginDvi{\special{pdf: tounicode UTF8-UCS2}} works fine with an Omega
 generated file.

BTW, xdvipdfmx adds an \n at the end of the CreationDate field, such as
"/CreationDate (Wed Jun 21 21:44:35 2006\n)". AFAIK this should be removed.

Thanks for your help,
