John Vines commented on ACCUMULO-739:
-------------------------------------
Escaping will make parsing substantially more complicated, especially if you
start going into nested quotations with some OTHER form of escaping. Perhaps an
alternative for supporting a larger alphabet would be to adopt a custom
encoding which ensures that no multi-byte characters consist of one of our
reserved characters. This would allow us to continue to do speedy checks while
still expanding the user base outside of English without concerns of encodings
breaking their expressions.
