pdflatex -file-line-error -interaction=nonstopmode "\input
\detokenize{DieÜbung.tex}"

would work, and recent releases of auctex have been updated to work
with such files.

It's possible that we can make

pdflatex -file-line-error -interaction=nonstopmode "\input {DieÜbung.tex}"

with the braced form work but the primitive unbraced \input is very
hard to catch.
