Only if either (a) we encode the responses we send to the SMTP server
during handshake, or (b) SMTP servers support UTF-8 encoding in the
strings they expect to receive.

Lars said "encoding is local", which suggest that neither of the above
is true.  raw-text leaves the byte stream unchanged, and only converts
the EOL, so a netrc file encoded in some locale-specific way has a
better chance with SMTP servers from the same locale.

IOW, to answer your question, someone who knows more than I do about
communications with SMTP servers should tell us how, if at all,
non-ASCII characters are supposed to be handled when communicating
with the server.
