True if you want the domain of the function to include lowercase.  I never
do; e.g. I claim that the proper name for EOT is "^D" rather than "^d".  If
you're willing to make this restriction, then the XOR has the advantage of
allowing the use of CTRL('?') for DEL, which is a widely (though by no means
universally) accepted notation.
