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!

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 they 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. c C s^ y2 t | t � r" | j d � n t | d � } Wn t k rT t j | � � n X| j � j d � } | t k p | t k s� y t j | � j } Wq� t k r� q� Xn t j | | � | _ t j | j t t d f � \ } } } | s� | j } n | | _ | | _ t j | | � | _ t j | j | j � | _ t j | j | j � | _ d S( NR ( t isinstancet unicodet encodet UnicodeErrorR t CharsetErrort lowerR" R t codecst lookupt namet LookupErrort gett input_charsetR t BASE64t Nonet header_encodingt body_encodingR!

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 to False.
