Not really with TeX, I think. Probably more with LaTeX's inputenc and/or
something in your system. (So the texhax list may be more appropriate.)

Is test.tex encoded in utf-8? And the filename too? Because in this case
it should work (it does work for me btw).

Why is your latex inputing retex.tex??? Is it really compiling the
one-line file shown above? If so, there is something very strange with
your latex format. (Maybe you \dump'ed something as latex.fmt by mistake.)

This is a problem with LaTeX's inputenc (and btw it shows you didn't
load fontenc with T1, which is higly recommended for german.

My technical answer is above, now here is my advice: do *not* use
non-ascii characters in filenames anyway.
