Yes, however some software will label outgoing stuff as UTF-8 even if
actually it contains no non-ASCII characters. Then, other software
will assume that it cannot understand the message (either because it
assumes the charset label is correct or because it doesn't know that
it can understand "UTF-8" that contains no top-bit-set characters).
