My mistake, it's not "canonical equivalence" that Peter was talking about but "conformance" to standard,so that a process can claim a character sequence is the same character sequence as that which was passed to it.(Thus I assume that a process can treat these two sequences (containing canonically equivalent characters but one with noncharacters) as different character sequences but does not have to do so.)
