The former prints a byte with a particular value. It prints an 'A' on ASCII
systems and something else on EBCDIC systems.

The latter is meant to print a character 'A'. But to get the character 'A',
you can just write /usr/bin/printf "A\n" portably, everywhere. So there's no
need for the \u notation here.
