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
