Documentation

Specify whether to allow sending non-ASCII characters in mail.

If t, that means do allow it. nil means don't allow it. query means ask the user each time. mime means add an appropriate MIME header if none already present. The default is mime. Including non-ASCII characters in a mail message can be problematical for the recipient, who may not know how to decode them properly.

Probably introduced at or before Emacs version 20.4.
