Sure, but the cases I'm particularly thinking of are actually
programs, not interactive use.  I think it's better to get escape
codes, which can be reconstructed, than to get `?', which can't.  I
realize this won't work generally, and will be different for Emacs 22.
In Emacs 22, it would be reasonable to do what yudit does (as far as I
remember) and write representations of the unicodes involved as \uxxxx
or similar.

What concept do you mean, exactly?
