      We need ceil(log2(0x10FFFF)) = 21 bits, or, more realistically, 24
      bits, or, even more realistically, 32 bits. I don't think we need to
      worry about memory consumption for the display of characters though.
      At least on any modern system. Perhaps the MS-DOS port needs special
      treatment...
