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;
