[tex-live] hyperref/puenc.def broken after upgrade

[Pander]

Hi all,

XeLaTeX (and probably more) is not working for all my documents after I
upgraded today. The error is:

Messages for file
/usr/local/texlive/2012/texmf-dist/tex/latex/hyperref/puenc.def:
! LaTeX Error: Missing \begin{document}.
See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.

                                       U}{\9043\223}%* U+2393

How can this be fixed?

Thanks,

Pander
