Thanks.

wxLua uses only lua strings, to save space, easier calls to wxWidgets
functions, and whatnot. It would be very easy to wrap wxStrings
however, but there's a lot of functions and it might be too much
bloat. We use the two functions wx2lua and lua2wx, see the top of
modules/wxlua/include/wxlstate.h.

You can also just use wxLua's binding generator instead of tolua++.
It's really easy to create the interface files and run the generator.
Take a look at bindings/wxstc for an example of how to write the rules
file for a smaller semi-separate library. See also the docs about our
binding generator.

No, see above, we don't have any wxStrings and the conversion of the
userdata in lua might be tricky.
