To decode the Subject =?iso-8859-2?Q?=... in email in python

[Dan Polansky]

When parsing messages using python's libraries email and mailbox, the
subject is often encoded using some kind of = notation. Apparently, the
encoding used in this notation is specified like =?iso-8859-2?Q?=... or
=?iso-8859-2?B?=. Is there a python library function to decode such a
subject, returning a unicode string? The use would be like

human_readable = cool_library.decode_equals(message['Subject'])

Thank you, Dan

human_readable = unicode(new_header)

That's RFC 2047 encoding, both examples introduce an ISO8859-2
string, the first variant says it's ascii-ized using
"Q"uoted-Printable, the other says the string is "B"ase64-encoded.

Is there a python library function to decode such a
subject, returning a unicode string? The use would be like

human_readable = cool_library.decode_equals(message['Subject'])

quoting from http://docs.python.org/lib/module-email.Header.html
[('p\xf6stal', 'iso-8859-1')]

Here is some code from a front end to Mailman moderation pages:

import email.Header
hdr = email.Header.make_header(email.Header.decode_header(sub))

Max, thanks; that was helpful. Roman, your explanation was helpful as
well. Dan
