19 This class creates unstructured E-mail header. Three arguments are
20 provided to the constructor: the header's name, its content, and the
21 content's character set. Non-US-ASCII portions of the contents are
22 encoded according to RFC 2047[1].
23
24 The fourth argument to the constructor is optional. If not an empty
25 string, it identifies the content's language, as described in section 5
26 of RFC 2231[2].
27
28 This is not the appropriate class to create structured MIME headers, or
29 address list headers. Use mail::Header::addresslist(3x) to create
30 headers that contain E-mail addresses. Use mail::Header::mime(3x) to
31 create structured MIME headers.
32
33 The toString() returns the header as a single text string: “name:
34 value”. Long headers are folded at the nearest whitespace.
