[Dev-luatex] Problem with a test with ^^-notation.

[Ulrike Fischer]

Hello,


I ran into a problem with the LaTeX-package listing related to the
handling of extendedchars (it can be easily avoid by using
extendedchars=false).


I think I have tracked down the problem to the following difference
between luatex and pdftex/xetex:

\documentclass{article}
\begin{document}
\catcode`\^^00=13
\ifnum`^^00=0 ja \else nein \fi

\end{document}

When processed with LaTeX or XeLaTeX I get a document with "ja".
Luatex gives "nein". Is this difference to be expected?
