I think you should make sure your "port" doesn't break libraries that
use strings for non-text data. For examples, you can try to use the io
library on binary files (use one of the (de)serialization libraries
available around), or LuaSocket on binary protocols.

By the way, what's the goal of such a modification of Lua ? If all you
need is being able to use Unicode filenames on windows, a simpler
approach is to assume filenames passed to Lua are in utf-8 format, and
convert it just when necessary when accessing the filesystem (in just
a very few places in Lua source code). I have a patch doing that if
anyone is interested.
