Email::MIME::RFC2047::Encoder(3)

NAME
Email::MIME::RFC2047::Encoder - Encoding of non-ASCII MIME headers

VERSION
version 0.97

SYNOPSIS
    use Email::MIME::RFC2047::Encoder;

    my $encoder = Email::MIME::RFC2047::Encoder->new(
        encoding => 'utf-8',
        method   => 'Q',
    );

    my $encoded_text   = $encoder->encode_text($string);
    my $encoded_phrase = $encoder->encode_phrase($string);

DESCRIPTION
This module encodes non-ASCII text for MIME email message headers according to RFC 2047.

CONSTRUCTOR

  new
    my $encoder = Email::MIME::RFC2047::Encoder->new(
        encoding => $encoding,
        method   => $method,
    );

Creates a new encoder object.

encoding specifies the encoding ("character set" in the RFC) to use. This is passed to Encode. See Encode::Supported for supported encodings.

method specifies the encoding method ("encoding" in the RFC). Must be either 'B' or 'Q'.

If both encoding and method are omitted, encoding defaults to 'utf-8' and method to 'Q'. If only encoding is omitted, it defaults to 'utf-8'. If only method is omitted, it defaults to 'B'.

METHODS

  encode_text
    my $encoded_text = $encoder->encode_text($string);

Encodes a string for use in any Subject or Comments header field, any extension message header field, or any MIME body part field for which the field body is defined as "unstructured" (RFC 2822) or *text (RFC 822). $string is expected to be an unencoded Perl string.

This method tries to use the MIME encoding for as few characters of the input string as possible. So the result may consist of a mix of encoded and unencoded words.

The source string is trimmed and any whitespace is collapsed. The words in the result are separated by single space characters without folding of long lines.

  encode_phrase
    my $encoded_phrase = $encoder->encode_phrase($string);

Encodes a string that may replace a "phrase" token (as defined by RFC 2822), for example, one that precedes an address in a From, To, or Cc header.

This method works like encode_text but additionally converts remaining text that contains special characters to "quoted-string"s.
