The syntax for the Warning response-header, in the case of a character
set different from ISO-8859-1, conflicts with RFC 1522 as clarified
by draft-ietf-822ext-mime-hdrs-00.txt. If HTTP/1.1 is meant to allow
encoded-words in a quoted-string, this should be clearly identified
as a deviation from the rules in RFC 1522 and its successor.

> If a character set other than ISO-8599-1 is used, it MUST be encoded in
> the warn-text using the method described in RFC 1522 [14].
