Returns a list of (decoded_string, charset) pairs containing each of the
decoded parts of the header. Charset is None for non-encoded parts of the
header, otherwise a lower-case string containing the name of the character
set specified in the encoded string.
An email.errors.HeaderParseError may be raised when certain decoding error
occurs (e.g. a base64 decoding exception).

decode_header() takes a header value string and returns a sequence of
pairs of the format (decoded_string, charset) where charset is the string
name of the character set.
This function takes one of those sequence of pairs and returns a Header
instance. Optional maxlinelen, header_name, and continuation_ws are as in
the Header constructor.

d S( s Create a MIME-compliant header that can contain many character sets.
Optional s is the initial header value. If None, the initial header
value is not set. You can later append to the header with .append()
method calls. s may be a byte string or a Unicode string, but see the
.append() documentation for semantics.
Optional charset serves two purposes: it has the same meaning as the
charset argument to the .append() method. It also sets the default
character set for all subsequent .append() calls that omit the charset
argument. If charset is not provided in the constructor, the us-ascii
charset is used both as s's initial charset and as the default for
subsequent .append() calls.
The maximum line length can be specified explicit via maxlinelen. For
splitting the first line to a shorter value (to account for the field
header which isn't included in s, e.g. `Subject') pass in the name of
the field in header_name. The default maxlinelen is 76.
continuation_ws must be RFC 2822 compliant folding whitespace (usually
either a space or a hard tab) which will be prepended to continuation
lines.
errors is passed through to the .append() call.

Optional charset, if given, should be a Charset instance or the name
of a character set (which will be converted to a Charset instance). A
value of None (the default) means that the charset given in the
constructor is used.
s may be a byte string or a Unicode string. If it is a byte string
(i.e. isinstance(s, str) is true), then charset is the encoding of
that byte string, and a UnicodeError will be raised if the string
cannot be decoded with that charset. If s is a Unicode string, then
charset is a hint specifying the character set of the characters in
the string. In this case, when producing an RFC 2822 compliant header
using RFC 2047 rules, the Unicode string will be encoded using the
following charsets in order: us-ascii, the charset hint, utf-8. The
first character set not to provoke a UnicodeError is used.
Optional `errors' is passed as the third argument to any unicode() or
ustr.encode() call.

S( s� Encode a message header into an RFC-compliant format.
There are many issues involved in converting a given string for use in
an email header. Only certain character sets are readable in most
email clients, and as header strings can only contain a subset of
7-bit ASCII, care must be taken to properly convert and encode (with
Base64 or quoted-printable) header strings. In addition, there is a
75-character length limit on any given encoded header field, so
line-wrapping must be performed, even with double-byte character sets.
This method will do its best to convert the string to the correct
character set used in email, and encode and line wrap it safely with
the appropriate scheme for that character set.
If the given charset is not known or an error occurs during
conversion, this function will return the header untouched.
Optional splitchars is a string containing characters to split long
ASCII lines on, in rough support of RFC 2822's `highest level
syntactic breaks'. This doesn't affect RFC 2047 encoded lines.
