RFC 1522

No, 1522 was designed for something far more restrictive than a simple
7-bit channel. It was designed for email headers (e.g. To:, Cc:, From:,

In these headers, characters such as comma, '<', '>', '(', ')' and so on
have a special meaning, and there is a *lot* of software out there that
does stuff with these characters. RFC 1522 has a lot of rules for this
type of thing.

So, even if you have an 8-bit email channel, RFC 1522 is needed.
