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 
always try to use the message body's encoding for the footer or 
heading. If that fails, and if the message body's encoding is US-
ASCII, the system can try to edit the message body to use the footer's 
or heading's encoding. Should the system try to impose the footer's 
or headings's encoding on the message body? [N]> y
Behavior when modifying headers: Use encoding of message body
Behavior for untagged non-ASCII headers: Impose encoding of message 
body. Behavior for mismatched footer or heading encoding: Try both 
body and footer or heading encodings
