Back to the subject line...

I still haven't seen a solution on how to be able to use 8-bit coded characters in the subject line. I have several php webapps that produces e-mails, and none of these seem to be capable of making an e-mail subject that includes our Swedish characters 'å ä ö Å Ä Ö'. I get e-mails daily WITH those chars. In the subject, so it certainly is possible. I looked in the header info in one of these e-mails, and the subject in the header is "Subject: =?iso-8859-1?Q?Fl=E4kts_ljudniv=E5?=" Where the subject is displayed as "Fläkts ljudnivå". Any ideas?
