alphanumerics in mails

[Ulf Engstrøm]

I've made a small mail-client which is working very good, except for when I
get mails with alphanumerics (which happens quite often since I'm in
scandinavia;).
If I send a mail with subject:
'Ett å'
The subject line in my mailclient will say:
'=?iso-8859-1?Q?Ett_=E5?='
Is there some kind of parser for this, has someone made anything like this
or do I have to make one?
Handling my mail uses poplib,cgi,multifile and mimetools.
Regards
Ulf
