'%' shouldn't present any problems - you can use it now in Mercury
programs if you are feeling brave.

The real question is whether we should
(1) require char literals to be single character singly quoted atoms and
have multi-character literals be function symbols or
(2) use a different quoting scheme for function symbols containing odd
characters.

Of course, unicode will probably throw a few spanners in the works
either way...
