We have to deal with wide characters on windows when it comes to filenames. The same is true for
the commandline and environment variables. Basically we go from utf8 to wide and back.

\stoptyping
Kind of tricky because quite some code (indirectness):
\starttyping
- lua load : via overload ?
- lua dofile : via overload -> loadstring
- lua require : via overload ?
\stoptyping
So: do we patch lua (fopen) or just copy? We can actually assume flat ascii files for libraries
and such so there is no real need unless we load job related files.
I will probably reshuffle some code and maybe more some more here; once I'm sure all works out
well.
