The error message is some strange mixture of german and english, so this what the error message is supposed to look like:

That's a sign that you're running R with options("encoding") set to 
something other than UTF-8, but your input file is UTF-8.  It should be 
fine if, before running Sweave,
you run

options(encoding="UTF-8")

I don't know if this is possible using "R CMD Sweave", but you can 
always put together your own command line version using Rscript or "R 
--slave".
