The integer specifies the width of field which will be filled with a

A positive value means padding SPCs on the right if necessary.

A negative value means padding SPCs on the left if necessary. If a

\(1) Decode quoted encoded-words, which violates RFC 2047.

Good example:
	From: Kazu Yamamoto (=?ISO-2022-JP?B?GyRCOzNLXE9CSScbKEI=?=)
		<kazu@example.org>
Bad example:
	From: Kazu Yamamoto (\"=?ISO-2022-JP?B?GyRCOzNLXE9CSScbKEI=?=\")
		<kazu@example.org>

\(2) Decode raw non-ASCII text, which violates RFC 822.
This is typically found in Subject: field.

Good example:
	Subject: =?iso-2022-jp?B?GyRCJEYkOSRIGyhC?=
Bad example:
	Subject: Raw non-ASCII text.

\(3) Decode invalid MIME parameters, which violates RFC 2231.
\(i)  Raw text.
\(ii) Encorded-word defined in RFC 2047.

Good example:
	Content-Disposition: attachment;
	 filename*=iso-2022-jp''%1B%24B%24F%249%24H%1B%28B

Bad example
	Content-Disposition: attachment;
	 filename=\"=?iso-2022-jp?B?GyRCJEYkOSRIGyhC?=\"

=(4) Decode invalid non-ASCII MIME body, whose charset is US-ASCII or
not present.

Good example:
	Content-Type: text/plain; charset=ISO-2022-jp

	ISO-2022-JP text

Bad example:
	Content-Type: text/plain

	ISO-2022-JP text

\(5) Decode invalid non-ASCII text, whose charset is UTF-8 or not present.

Good example:
	Content-Type: text/plain; charset=ISO-8859-15

	ISO-8859-15 text

Bad example:
	Content-Type: text/plain; charset=UTF-8
