Lua identifiers cannot have UTF-8 characters that are not ASCII letters

There's no reason you can't write print(myTable['(╯°□°）╯︵ ┻━┻']), though.

It does in the lexer. See luaX_newstring in the source. It calls
luaS_newlstr which interns short strings.

Would interning longer strings in the source code present any problems?
