Sorry, I was smelling something else. :-o  What is it about the Send
key that makes the lightbulb go on over my head? :-}

0244 is an ISO-8859-1 (nee Latin-1, nee ASCII) "generic currency sign"
-- a graphical character.  0237 is undefined, non-graphical,
slashified.

    https://en.wikipedia.org/wiki/ISO/IEC_8859-1

So I think we're OK.

I'm probably NOT supposed to say "Latin-1" or even "ASCII".  Our
documentation mentions only "ISO-8859-1".

If you are looking for something to fix, the documentation also
says this:

  @strong{Note}: Although character objects can represent all of Unicode,
  the model of alphabetic case used covers only @acronym{ASCII} letters,
  which means that case-insensitive comparisons and case conversions are
  incorrect for address@hidden letters.  This will eventually be
  fixed.

You are forewarned.
