If a header is modified, encode the new header in the same encoding as
the message body? (Some MUAs incorrectly handle headers encoded in a

in the same encoding as the message body may cause certain characters in the modified
header to be lost.) [Y]>
If a non-ASCII header is not properly tagged with a character set and
is being used or modified, impose the encoding of the body on the
header during processing and final representation of the message?
(Many MUAs create non-RFC-compliant headers that are then handled in
an undefined way. Some MUAs handle headers encoded in character sets
that differ from that of the main body in an incorrect way. Imposing the encoding of the
body on the header may encode
the header more precisely. This will be used to interpret the content of headers for
processing, it will not modify or rewrite the header
unless that is done explicitly as part of the processing.) [Y]>
Footers or headings are added in-line with the message body whenever
possible. However, if the footer or heading is encoded differently
than the message body,and if imposing a single encoding will cause
loss of characters, it will be added as an attachment. The system will
