[Imap-protocol] non-ASCII byte sequences in IMAP?

[Bill Janssen]

I'm looking at the various uses of CHARSET in IMAP.  It appears to
occur in two places: the SEARCH command, and the FETCH response.  I
think it can also appear in the message literal in the APPEND command.
So those are the only three places where an IMAP server (or client)
might see non-ASCII byte streams.  Everything else is ASCII.

Is that correct?
