Yes, that could work too.  (It would break the implementation for
modes in which trigraphs are disabled, but since such modes are
non-conforming it's not relevant to the current disucssion.)

Still, it doesn't provide what I'm looking for: an example of an
existing real-world conforming implementation that would not be
conforming if '@' et al were added to the basic character set.
