Also,

      BASE32DIGIT = DIGIT
                  / "A" / "B" / "C" / "D" / "E" / "F" / "G" / "H"
                  / "I" / "J" / "K" / "L" / "M" / "N" / "O" / "P"
                  / "Q" / "R" / "S" / "T" / "U" / "V"

in RFC 2938.  (I won't claim this is the best possible arrangement, or in 
any way an official preference;  it just seemed to be an easy way at the 
time, kind of like an extension of hexadecimal.  Hand transcription was not 
a significant requirement here.)
