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


      use MIME::QuotedPrint;

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


     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 char-
     acters in the ASCII character set.  Each non-printable char-
     acter (as defined by English Americans) is represented by a
     triplet consisting of the character "=" followed by two hex-
     adecimal digits.

     The following functions are provided:

     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 con-
         sumption. 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 char-
         acter.  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 ori-
         ginal data is encoded as well.

         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;
