Exactly my point: no-one should silently assume char is 8 bits, but
instead look into CHAR_BITS, as defined by the implementation's
<limits.h> to *check* if it really is 8 bits. Or, even better, look up
that value and use it to scale your arrays, if you really feel you
can't allow wasting the bits beyond the 8th that are present in a
char.
