Plain character is an abomination.  It is particularly unsuited for
character data.  You can get singed.  ;-)

All three are integer types.  All three are 1 byte wide ("byte" does
not mean "8 bits").

I'm not sure what you mean.  There's no such thing as "byte."
uint8_t?  Not guaranteed to exist.  unint_least8_t?  That would work,
but I fear relatively few even know it exists, let alone how to use
it...
