NAME
       MIME::QuotedPrint - Encoding and	decoding of quoted-printable strings

SYNOPSIS
	use MIME::QuotedPrint;

	$encoded = encode_qp($decoded);
	$decoded = decode_qp($encoded);

DESCRIPTION
       This module provides functions to encode	and decode strings into	and
       from the	quoted-printable encoding specified in RFC 2045	- MIME
       (Multipurpose Internet Mail Extensions).	 The quoted-printable encoding
       is intended to represent	data that largely consists of bytes that
       correspond to printable characters in the ASCII character set.  Each
       non-printable character (as defined by English Americans) is
       represented by a	triplet	consisting of the character "="	followed by
       two hexadecimal digits.

       The following functions are provided:

       encode_qp( $str)
       encode_qp( $str,	$eol)
       encode_qp( $str,	$eol, $binmode )
	   This	function returns an encoded version of the string ($str) given
	   as argument.

	   The second argument ($eol) is the line-ending sequence to use.  It
	   is optional and defaults to "\n".  Every occurrence of "\n" is
	   replaced with this string, and it is	also used for additional "soft
	   line	breaks"	to ensure that no line end up longer than 76
	   characters.	Pass it	as "\015\012" to produce data suitable for
	   external consumption.  The string "\r\n" produces the same result
	   on many platforms, but not all.

	   The third argument ($binmode) will select binary mode if passed as
	   a TRUE value.  In binary mode "\n" will be encoded in the same way
	   as any other	non-printable character.  This ensures that a decoder
	   will	end up with exactly the	same string whatever line ending
	   sequence it uses.  In general it is preferable to use the base64
	   encoding for	binary data; see MIME::Base64.

	   An $eol of "" (the empty string) is special.	 In this case, no
	   "soft line breaks" are introduced and binary	mode is	effectively
	   enabled so that any "\n" in the original data is encoded as well.

       decode_qp( $str )
	   This	function returns the plain text	version	of the string given as
	   argument.  The lines	of the result are "\n" terminated, even	if the
	   $str	argument contains "\r\n" terminated lines.

       If you prefer not to import these routines into your namespace, you can
       call them as:

	 use MIME::QuotedPrint ();
	 $encoded = MIME::QuotedPrint::encode($decoded);
	 $decoded = MIME::QuotedPrint::decode($encoded);

       Perl v5.8 and better allow extended Unicode characters in strings.
       Such strings cannot be encoded directly,	as the quoted-printable
       encoding	is only	defined	for single-byte	characters.  The solution is
       to use the Encode module	to select the byte encoding you	want.  For
       example:

	   use MIME::QuotedPrint qw(encode_qp);
	   use Encode qw(encode);

	   $encoded = encode_qp(encode("UTF-8",	"\x{FFFF}\n"));
	   print $encoded;
