Another option for Unicode in Lua is to use RTF-8. Because Lua is 8-bit
clean, most parts of Lua should work without change when fed with RTF-8
strings. As far as I can see, the lexer should also work OK (assuming that
non-ascii chars only happen inside string literals or comments). Only the
string library would fail miserably (even strlen!). But, depending on how
much you use from it, it should be easy to convert those functions to
RTF-8.
