Right.  DUDE and AMC-ACE-W use bitwise operations, and can therefore use
only 32 characters.  Since 4 characters had to be left out anyway, it
made sense to leave out the visually confusing ones.

AMC-ACE-Z, on the other hand, does not use bitwise operations, and can
therefore utilize all the characters.
