About that point, does anyone know anything about support for Unicode in
Linux? (More specifically, where we could find a complete implementation
of "wchar.h"?)

As lhf said, you can use strings for binary I/O. But, in DOS, you still
need to open the file in "binary" mode. Lua 3.2 comes with a new function,
"openfile", where you provide an explicit "mode" string.
