>>> address = u'"Jörg Nørgens" <[EMAIL PROTECTED]>'.encode('latin-1')
>>> address
'"J\xf6rg N\xf8rgens" <[EMAIL PROTECTED]>'
>>> from email.Header import Header
>>> hdr = str(Header(address, 'latin-1'))
>>> hdr
'=?iso-8859-1?q?=22J=F6rg_N=F8rgens=22_=3Cjoerg=40nowhere=3E?='
Is this not correct?
At least roundtripping works:
>>> from email.Header import decode_header
>>> encoded, coding = decode_header(hdr)[0]
>>> encoded, coding
('"J\xf6rg N\xf8rgens" <[EMAIL PROTECTED]>', 'iso-8859-1')
>>> encoded.decode(coding)
u'"J\xf6rg N\xf8rgens" <[EMAIL PROTECTED]>'
And parsing the address works too.
>>> from email.Utils import parseaddr
>>> parseaddr(encoded.decode(coding))
(u'J\xf6rg N\xf8rgens', u'[EMAIL PROTECTED]')
>>>
