Thanks for working on this. This patch uses native LuaTeX support for
Unicode. If we wanted to support this in texinfo.tex, it should
probably be optional. The only think I can think of right now would be
an option enabled something like

@tex
\global\texiluatexnativeutfviiitrue
@end tex

Unless someone has a nicer way of doing it?

Maybe whether a "@documentencoding UTF-8" line is given should affect
whether native Unicode is used by default.

The changes in the patch should be conditional upon whether native
Unicode support is enabled, and whether LuaTeX is being used.

Are these changes likely to work for most LuaTeX installations, e.g.
will luaotfload.sty exist for everyone?
