I would say this means that your shell is passing the file name to
luatex 8-bit encoded and the byte sequence is no valid ut8. I get
the same on win7 while on winxp the name works fine. 

I don't think that this is the same problem as the xetex error. 

It is simply due that as not every byte sequence is valid utf8
applications that expect utf8 have problems 8-bit-input. A similar
problem just appeared with pdflatex + miktex. If you use e.g.
\input{tüte} in an 8-bit-encoded (e.g. ansinew) document you get the
equivalent windows api error:

% latex.exe: Windows API error 1113: Für das Unicode
% -Zeichen ist kein zugeordnetes Zeichen in der Mehrbytecodepage
% Drücken Sie eine beliebige Taste . . .

Whoever thought that utf8 and unicode would make it easier to use
file names with non-ascii chars should reconsider this view.
