SYNOPSIS



 use MIME::EcoEncode::Param;
 $encoded = mime_eco_param($str, UTF-8);       # encode utf8 string
 $encoded = mime_eco_param($str, "UTF-8XX");   # 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)

 $decoded = mime_deco_param($encoded);           # decode encoded string

DESCRIPTION

This module implements RFC 2231 Mime Parameter Value Encoding.

    Options



  $encoded = mime_eco_param($str, $charset, $lf, $bpl);
               # $charset : UTF-8 / "UTF-8XX" /
               #            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-8ja", "\n", 33), "\n";



Ex1’s output:



   filename*0*=UTF-8ja%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==?="
