Yes, Ada does support machines that don't have 8 bit bytes. There have
existed Ada compilers for machines that don't have 8-bit bytes. For
instance, we made a version of Janus/Ada 95 for the Unisys U2200, which
has 36-bit words, and to a lesser extent, 6 and 9 bit bytes.

Types like Character and Stream_Element can have any size appropriate to
the hardware. The main problem is importing and exporting data created
in such formats.
