Problem with characters in Flash mail form

Hi
I have posted this on the server-side forum earlier (http://www.kirupa.com/forum/showthread.php?p=824417#post824417) without finding an answer but thought I’d try here in case it has something to do with the Flash-part.

My mailform and php works fine except that the letters å ä ö don’t display properly. I have tried different ways of changing the php-script with urlencode and urldecode without success.

The letters show right when filling in the form, it’s only in the received mail that they show up wrong. Could it have something to do with Flash? I have tried it with different fonts (no difference) and the text rendered as html.
THe letters display as follows: å becomes Ã¥, ä becomes ä and ö becomes ö

Anyone know of this?
