As I wrote, Tanaka-san's patch was once applied on LuaTeX (0.78.0).
However, ConTeXt-minimal installer and ConTeXt mkiv did not work.
Further, Hans dislikes to touch command-line arguments.

In the latest dev version (r5033: luatex-dev-w32.tar.xz,
luatex-dev-w64.tar.xz), I provide a luatex which uses Tanaka-san's
patch if ond only if
(1)
command_line_encoding = utf8
is set in texmf.cnf
(2) the first argument (argv[1]) is --cmdx.

Therefore, I expect lualatex --cmdx  ... behaves like the
lualatex  ... in MikTeX.

As the default behaviors are not changed, ConTeXt mkiv works fine.

Thanks,
Akira
