What should it print?  Strictly, speaking "^/" is not a real control
character.  The SLang_process_keystring converts ^X to an unsigned
byte value using the algorithm

   (unsigned char) (X - 'A' + 1)

This mechanism works for valid control characters ^A-^Z as well as ^@,
^[, ^\, ^], ^^, and ^_.  For ^/, the result is

   (unsigned char) ('/' - 'A' + 1)
    = (unsigned char) (-17)
    = 0xEF

This interface makes no attempt at converting bytes to characters.
That is, it does not produce the two byte sequence <C3><AF>.  Is that
what you were expecting?
