Well, it's mandated by POSIX to be 8 bits and in general a quite
reasonable assumption (if targeting POSIX systems) but not necessarily
true elsewhere... and if you depend on the signedness of char you are
doing it wrong too. If you want 8 unsigned bits you should use uint8_t
instead of char. In that regard it's quite similar to the int
"problem". In either case there is a proper solution in C that is
working on all conforming systems.

Right shifts of negative integers is UB in C (and not necessarily
sign-extended) if that's what you mean. We are also quite off-topic
already IMHO...
