Description (partial)

Character encoding during modification of header values is dependent on the CLI "localeconfig" setting:
"Behavior when modifying headers: Use encoding of a message body >  Y/N"

Headers which are not UTF-8 encoded are encoded using UTF-8, despite the above setting being set to "Y", during filter actions which modify headers.

When the same header value is modified by using a filter's "insert-header()" action, the encoding is done using the message body's encoding type as expected.

"localeconfig"'s "Behavior when modifying headers:" setting is configured to "Use encoding of a message body"
and the message body encoding is not UTF-8.
