it's easier to implement but completely unreasonable.  it's quite
permissable, and not unusual, for English text in plain ASCII to be
encoded in base64

(this usually happens because the message is being sent from a MUA
that normally uses a different charset, that is best encoded in base64.
but it happens even if the message is entirely ASCII)
