charset is the input character set, and must be the canonical name of a
character set.
Optional header_enc and body_enc is either Charset.QP for
quoted-printable, Charset.BASE64 for base64 encoding, Charset.SHORTEST for
the shortest of qp or base64 encoding, or None for no encoding. SHORTEST
is only valid for header_enc. It describes how message headers and
message bodies in the input charset are to be encoded. Default is no
encoding.
Optional output_charset is the character set that the output should be
in. Conversions will proceed from input charset, to Unicode, to the
output charset when the method Charset.convert() is called. The default
is to output in the same character set as the input.
Both input_charset and output_charset must have Unicode codec entries in
the module's charset-to-codec mapping; use add_codec(charset, codecname)
to add codecs the module does not know about. See the codecs module's
documentation for more information.

s? Map character sets to their email properties.
This class provides information about the requirements imposed on email
for a specific character set. It also provides convenience routines for
converting between character sets, given the availability of the
applicable codecs. Given a character set, it will do its best to provide
information on how to use that character set in an email in an
RFC-compliant way.
Certain character sets must be encoded with quoted-printable or base64
when used in email headers or bodies. Certain character sets must be
converted outright, and are not allowed in email. Instances of this
module expose the following information about a character set:
input_charset: The initial character set specified. Common aliases
are converted to their `official' email names (e.g. latin_1
is converted to iso-8859-1). Defaults to 7-bit us-ascii.
header_encoding: If the character set must be encoded before it can be
used in an email header, this attribute will be set to
Charset.QP (for quoted-printable), Charset.BASE64 (for
base64 encoding), or Charset.SHORTEST for the shortest of
QP or BASE64 encoding. Otherwise, it will be None.
body_encoding: Same as header_encoding, but describes the encoding for the
mail message's body, which indeed may be different than the
header encoding. Charset.SHORTEST is not allowed for
body_encoding.
output_charset: Some character sets must be converted before the can be
used in email headers or bodies. If the input_charset is
one of them, this attribute will contain the name of the
charset output will be converted to. Otherwise, it will
be None.
input_codec: The name of the Python codec used to convert the
input_charset to Unicode. If no conversion codec is
necessary, this attribute will be None.
output_codec: The name of the Python codec used to convert Unicode
to the output_charset. If no conversion codec is necessary,
this attribute will have the same value as the input_codec.

This is either the string `quoted-printable' or `base64' depending on

If convert is True, the string will be converted from the input
charset to the output charset automatically. This is not useful for
multibyte character sets, which have line length issues (multibyte
characters must be split on a character, not a byte boundary); use the
high-level Header class to deal with these issues. convert defaults
