If anyone ever assumed UTF-8 is compatible with ASCII, they were
mistaken. An ASCII processor can expect to receive octets strictly in
the range 0 - 127, period, whereas clearly UTF-8 data can contain octets
outside that range.
ASCII is forward compatible with UTF-8 (a UTF-8 processor can process
ASCII data), not the other way around.
