- An 'encoded-word' MUST NOT appear within a 'quoted-string'.
So, there does seem to be a bug in the mailer used by the person sending the message.
Yes, but we'd still have this problem even if this wasn't inside a quoted-string, because encoded-words themselves can contain any characters. Also in RFC 2047:
NOTE: Decoding and display of encoded-words occurs *after* a structured field body is parsed into tokens. It is therefore possible to hide 'special' characters in encoded-words which, when displayed, will be indistinguishable from 'special' characters in the surrounding text. For this and other reasons, it is NOT generally possible to translate a message header containing 'encoded-word's to an unencoded form which can be parsed by an RFC 822 mail reader.
