Internationall letters in PHP?!?

Does anybody know where and what i have to do to make a PHP that takes info from a htm from a swf to sen internationall letters?! I used the guide http://www.kirupa.com/developer/actionscript/flash_php_email.htm

The guide works, it’s just that the mail i get after sending something to myself looks like this:

“<TEXTFORMAT LEADING=“2”><P ALIGN=“LEFT”><FONT FACE=“Verdana” SIZE=“10” COLOR=”#000000">fan, varför fungerar inte åäö</FONT></P></TEXTFORMAT>"…

What have I missed?
