The Posix standard is pretty explicit that printf(1), because of the
underlying formatted output functions it uses, is byte-oriented.  There
is support for wide characters, but not for multibyte ones.  For instance,
strings printed with %s are bytes, precisions determine the number of
bytes printed, and return values are numbers of bytes.

I will take a look at the standard and see what it says about bytes in
the format string.
