First, don't use luainputenc in new documents (luatex is utf-8 by
default, so it doesn't make sense anyway). Second, use locals in your
lua code to avoid conflicts (running your code with texlive-2010, your
"file" clashes with lualibs "file" modules causing luaotfload errors), it
is always good practice to limit the scope of your variables.

Tat being said, I get the omegas too (IIRC this is omega/luatex default
unknown character or something).
