I understand your problem, but the real problem is with your MUA that
creates a message with characters outside the [#1..#127] range in the
RFC2822 section 2.2 says in part:
Header fields are lines composed of a field name, followed by a colon
(":"), followed by a field body, and terminated by CRLF. A field
name MUST be composed of printable US-ASCII characters (i.e.,
characters that have values between 33 and 126, inclusive), except
RFC822 uses different language but also restricts the characters to the
printable US-ASCII range.
RFC2047 provides a method for encoding characters outside this range
into message headers using either base64 or quoted-printable encoding.
This gives headers that look for example like:
Subject: =?iso-8859-13?q?Subject= with= =c0= Baltic= character?=
Of course, there are major problems because not all MUAs create headers
in this way and not all MUAs understand them, but this isn't really a
