Decode email subjects into unicode

[Laszlo Nagy]

Hi All,

'm in trouble with decoding email subjects. Here are some examples:

=?koi8-r?B?4tnT1NLP19n Qz8zOyc3PIMkgzc HMz9rB1NLB1M7P? =
[Fwd: re:Flags Of The World, Us States, And Military]
=?ISO-8859-2?Q?=E9rdekes?=
=?UTF-8?B?aGliw6Fr?=

I know that "=?UTF-8?B" means UTF-8 + base64 encoding, but I wonder if
there is a standard method in the "email" package to decode these
subjects? I do not want to re-invent the weel.

Thanks,

Laszlo

The standard library function email.Header.de code_header will parse these
headers into an encoded bytestring paired with the appropriate encoding
specification, if any. For example:

>>raw_headers = [

.... '=?koi8-r?B?4tnT1NLP19n Qz8zOyc3PIMkgzc HMz9rB1NLB1M7P? =',
.... '[Fwd: re:Flags Of The World, Us States, And Military]',
.... '=?ISO-8859-2?Q?=E9rdekes?= ',
.... '=?UTF-8?B?aGliw6Fr?=' ,
.... ]

>>from email.Header import decode_header
for raw_header in raw_headers:

.... for header, encoding in decode_header(r aw_header):
.... if encoding is None:
.... print header.decode()
.... else:
.... print header.decode(e ncoding)
....
