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

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?
