Where did you get the Unicode string that doesn't work in your sample
program? Could you post one? I tried different things in wxGTK
compiled in Unicode, but I had no problem with the original conversion
code. I am not expereienced with Unicode so the original code was from
some posts on wx-users and the STC contrib about how to convert back
and forth.
Do we also need to care about embedded NULLS? There is a lua function
to get the string as well as it's length, maybe we should use that
too? Perhaps the unicode string had embedded NULLs?

Always wxConvUTF8 in Unicode? Not wxConvCurrent?
I don't understand why in non unicode you convert it to a WC array and
then back. You should be able to just to "return wxString(luastr)"
since everything is ASCII.

Originally:
wxConvertWX2MB == wxConvCurrent->cWX2MB(wchar_t* s)
cWX2MB returns wxUSE_UNICODE ? cWC2MB(wchar_t* psz) : psz
So again, always use wxConvUTF8?

I will try it in MSW in non unicode tomorrow and GTK w/ unicode tonight.
