Yes that makes sense. I got it right that the setting is global, so I
would have to reset it after the input?

Btw: Is is correct that the following code 

\documentclass{scrreprt}
\usepackage{fontspec}
\begin{document}
{\XeTeXdefaultencoding "cp1252"
 \XeTeXdefaultencoding "auto"}

test
\end{document}

gives the message 
### simple group (level 1) entered at line 5 ({)
### bottom level 

?
(It works fine if I add a \relax after the "auto").
