NAME

6       Encode::MIME::EncWords -- MIME 'B' and 'Q' header encoding
7       (alternative)
8

SYNOPSIS

10           use Encode::MIME::EncWords;
11           use Encode qw/encode decode/;
12
13           # decode header:
14           $utf8   = decode('MIME-EncWords', $header);
15
16           # encode header with default charset, UTF-8:
17           $header = encode('MIME-EncWords', $utf8);
18
19           # encode header with another charset:
20           Encode::MIME::EncWords->config(Charset => 'GB2312');
21           $header = encode('MIME-EncWords', $utf8);
22

ABSTRACT

24       This module implements MIME header encoding described in RFC 2047.
25       There are three variant encoding names and one shorthand special to a
26       charset:
27
28         Encoding name              Result of encode()     Comment
29         -------------------------------------------------------------------
30         MIME-EncWords              (auto-detect B or Q)
31         MIME-EncWords-B            =?XXXX?B?...?=         Default is UTF-8.
32         MIME-EncWords-Q            =?XXXX?Q?...?=                ,,
33         MIME-EncWords-ISO_2022_JP  =?ISO-2022-JP?B?...?=
34
35       All encodings generate the same result by decode().

DESCRIPTION

38       This module is intended to be an alternative of "MIME-*" encodings
39       provided by Encode::MIME::Header core module.  To find out how to use
40       this module in detail, see Encode.
41
42   Module specific feature
43       config(KEY => VALUE, ...);
44           Class method.  Set options by KEY => VALUE pairs.  Following
45           options are available.
46
47           Charset
48               [encode] Name of character set by which data elements will be
49               converted.  Default is "UTF-8".  On "MIME-EncWords-ISO_2022_JP"
50               it is fixed to "ISO-2022-JP".
51
52           Detect7bit
53               [decode/encode] Try to detect 7-bit charset on unencoded
54               portions.  Default is "YES".
55
56           Field
57               [encode] Name of the header field which will be considered on
58               the first line of encoded result in its length.  Default is
59               "undef".
60
61           Mapping
62               [decode/encode] Specify mappings actually used for charset
63               names.  Default is "EXTENDED".
64
65           MaxLineLen
66               [encode] Maximum line length excluding newline.  Default is 76.
67
68           Minimal
69               [encode] Whether to do minimal encoding or not.  Default is
70               "YES".
71
72           For more details about options see MIME::EncWords.

CAVEAT

75       •   The encoding modules for MIME header encoding are not the magic
76           porridge pot to cook complex header fields properly.
77
78           To decode address header fields (From:, To:, ...), at first parse
79           mailbox-list; then decode each element by encoding module.  To
80           encode them, at first encode each element by encoding module; then
81           construct mailbox-list of encoded elements.  To construct or parse
82           mailbox-list, some modules such as Mail::Address may be used.
83
84       •   Lines are delimited with LF ("\n").  RFC5322 states that lines in
85           Internet messages are delimited with CRLF ("\r\n").
