       MIME::EcoEncode::Param - RFC 2231 Encode/Decode

SYNOPSIS

        use MIME::EcoEncode::Param;
        $encoded = mime_eco_param($str, 'UTF-8');       # encode utf8 string
        $encoded = mime_eco_param($str, "UTF-8'XX'");   # XX is language
        $encoded = mime_eco_param($str, 'UTF-8*XX?B');  # "B" encoding
        $encoded = mime_eco_param($str, 'UTF-8*XX?Q');  # "Q" encoding
        $encoded = mime_eco_param($str, 'GB2312');      # euc-cn string
        $encoded = mime_eco_param($str, 'EUC-KR');      # euc-kr string
        $encoded = mime_eco_param($str, 'Big5');        # big5 string
        $encoded = mime_eco_param($str, 'Shift_JIS');   # cp932 string
        $encoded = mime_eco_param($str, 'ISO-2022-JP'); # 7bit-jis string

                                                        #   single-byte charset
                                                        #   (e.g. 'ISO-8859-1')

DESCRIPTION

       This module implements RFC 2231 Mime Parameter Value Encoding.

   Options
         $encoded = mime_eco_param($str, $charset, $lf, $bpl);
                      # $charset : 'UTF-8' / "UTF-8'XX'" /
                      #            'UTF-8*XX?B' / 'UTF-8*XX?Q' /
                      #            'GB2312' / 'EUC-KR' / 'Big5' /
                      #            'Shift_JIS' / 'ISO-2022-JP' / ...
                      #            (default: 'UTF-8')
                      #              Note: The others are all encoded as
                      #                    single-byte string.
                      # $lf      : line feed (default: "\n")
                      # $bpl     : bytes per line (default: 76)

         $decoded = mime_deco_param($encoded, $bq_on);
                      # $bq_on   : 1 : ON decode "B/Q" encoding
                      #            0 : OFF
                      #            (default: 1)

   Examples
       Ex1 - RFC 2231 encoding

         use MIME::EcoEncode::Param;
         my $str = " filename=\xe5\xaf\x8c\xe5\xa3\xab\xe5\xb1\xb1_2013.jpeg";
         print mime_eco_param($str, "UTF-8'ja'", "\n", 33), "\n";

       Ex1's output:

          filename*0*=UTF-8'ja'%E5%AF%8C;
          filename*1*=%E5%A3%AB%E5%B1%B1_;
          filename*2=2013.jpeg

       Ex2 - "Q" encoding (for Windows)

         use MIME::EcoEncode::Param;
         my $str = " name=\xe5\xaf\x8c\xe5\xa3\xab\xe5\xb1\xb1_2013.jpeg";
         print mime_eco_param($str, 'UTF-8?Q', "\n", 33), "\n";

       Ex2's output:

          name="=?UTF-8?Q?=E5=AF=8C=E5?=
          =?UTF-8?Q?=A3=AB=E5=B1=B1=5F20?=
          =?UTF-8?Q?13.jpeg?="

       Ex3 - "B" encoding (for Windows)

         use MIME::EcoEncode::Param;
         my $str = " name=\xe5\xaf\x8c\xe5\xa3\xab\xe5\xb1\xb1_2013.jpeg";
         print mime_eco_param($str, 'UTF-8?B', "\n", 33), "\n";

       Ex3's output:

          name="=?UTF-8?B?5a+M5aOr5bGx?=
          =?UTF-8?B?XzIwMTMuanBlZw==?="
