NAME

       Encode::MIME::EncWords -- MIME 'B' and 'Q' header encoding (alternative)

SYNOPSIS

           use Encode::MIME::EncWords;
           use Encode qw/encode decode/;

           # decode header:
           $utf8   = decode('MIME-EncWords', $header);

           # encode header with default charset, UTF-8:
           $header = encode('MIME-EncWords', $utf8);

           # encode header with another charset:
           Encode::MIME::EncWords->config(Charset => 'GB2312');
           $header = encode('MIME-EncWords', $utf8);

ABSTRACT

       This module implements MIME header encoding described in RFC 2047.  There are three
       variant encoding names and one shorthand special to a charset:

         Encoding name              Result of encode()     Comment
         -------------------------------------------------------------------
         MIME-EncWords              (auto-detect B or Q)
         MIME-EncWords-B            =?XXXX?B?...?=         Default is UTF-8.
         MIME-EncWords-Q            =?XXXX?Q?...?=                ,,
         MIME-EncWords-ISO_2022_JP  =?ISO-2022-JP?B?...?=

       All encodings generate the same result by decode().

DESCRIPTION

       This module is intended to be an alternative of "MIME-*" encodings provided by
       Encode::MIME::Header core module.  To find out how to use this module in detail, see
       Encode.

   Module specific feature
       config(KEY => VALUE, ...);
           Class method.  Set options by KEY => VALUE pairs.  Following options are available.

           Charset
               [encode] Name of character set by which data elements will be converted.  Default
               is "UTF-8".  On "MIME-EncWords-ISO_2022_JP" it is fixed to "ISO-2022-JP".

           Detect7bit
               [decode/encode] Try to detect 7-bit charset on unencoded portions.  Default is
               "YES".

           Field
               [encode] Name of the header field which will be considered on the first line of
               encoded result in its length.  Default is "undef".

           Mapping
               [decode/encode] Specify mappings actually used for charset names.  Default is
               "EXTENDED".

           MaxLineLen
               [encode] Maximum line length excluding newline.  Default is 76.

           Minimal
               [encode] Whether to do minimal encoding or not.  Default is "YES".

           For more details about options see MIME::EncWords.

CAVEAT

       •   The encoding modules for MIME header encoding are not the magic porridge pot to cook
           complex header fields properly.

           To decode address header fields (From:, To:, ...), at first parse mailbox-list; then
           decode each element by encoding module.  To encode them, at first encode each element
           by encoding module; then construct mailbox-list of encoded elements.  To construct or
           parse mailbox-list, some modules such as Mail::Address may be used.

       •   Lines are delimited with LF ("\n").  RFC5322 states that lines in Internet messages
           are delimited with CRLF ("\r\n").
