i believe (but can be wrong) when the Lua compiler scans for a string,
it grabs everything until it grabs the end quote, which can be ', " or
]==..==]. all these are ASCII values, whose octets have the eight bit
UTF8 was specifically formulated so that a multi-octet character can't
be mistaken for ASCII characters. to ensure that, every octet has the
eight bit set.
therefore, when a string starts with ", Lua will grab everything until
the next ", which can't be at the middle of a non-ASCII character.
similarly with single quotes and longstrings
so, i think you're safe.
