I came to the same conclusion, see my answer to Josephs mail.

This file was all I need to reproduce the problem (LF line ending, Linux):

\documentclass{article}
\XeTeXdefaultencoding "UTF-8"  
\usepackage{hyperref}
\begin{document}
\end{document}

The problem is not related to hyperref:

\documentclass{article}
\XeTeXdefaultencoding "UTF-8"
\AtBeginDocument{%
  \InputIfFileExists{t003.out}{}{}
}
\begin{document}
\end{document}

It shows the string "OT1/cm".

Or:

\documentclass{minimal}
\XeTeXdefaultencoding "UTF-8"
\AtBeginDocument{%
  \InputIfFileExists{t003.out}{}{}
}
\begin{document}
\end{document}

This shows "D at OT1m".
