Indeed. This caused me to insert an extra handling for german.sty.
But as you mentioned the use of \@santize is a better way to solve
the problem.

Well, I thought of this already, but didn't know which chars I had
to regard. I didn't know that \@sanitize is the macro I was looking
for.

Is there a way, to write a macro which can be used inside user-defined
macros, too? Perhaps, one could support a macro inside xindy.sty,
which can be used to define user-defined macros using \indexindy?

Well thanks a lot for this help. I implemented this version in the style
and it's doing fine. BTW: I often search various commands and infos in
the lt*.dtx-files. But there are too much to find the required information
in a tolerant time. Do you now, if there is a overview of the contents
of the dtx-file, somewhere in the net?
I won't post the new version right now, cause I'm currently doing
some minor changes on spacing and the .idx-output. I will post it
as soon as possible.
Best Regards,
Andi
