[texhax] unicode

[Alexander Grahn]

Thanks Phillip, for the hint.

I tried ^^@ as suggested on p. 45 of the TeXBook:

\documentclass{article}

\newwrite\outfile
\immediate\openout\outfile=out.txt
\immediate\write\outfile{^^@}
\immediate\closeout\outfile

\begin{document}
\end{document}

But again, TeX complains:

! Text line contains an invalid character.
l.5 \immediate\write\outfile{^^@
                                }
? 

The same happens if I write
^^00 instead of ^^@
(which, the TeXBook says, is the same)

:(
