Subject: [PATCH] Fix some XeTeX + TeX-fonts regressions introduced by fixing
 #9740.

hyperref expects LICR macros for non-ASCII chars in the PDF Header Information.
As hyperref provides good coverage for \inputencoding{utf8}, we try
this if the current input encoding does not support a character.

With XeTeX, we do not load inputenc and cannot use \inputencoding.
However, utf-8 works out of the box so we can write the content in UTF8.
