Mailer flash php Polish characters problem

Hi,
I used “Flash-Based Email Form Using PHP” by Senocular and I have a problem with Polish characters (eg. ł, ą, ę, ć, ż, etc…). I can type them in the form but when I read the email after sending it to my mailbox the email appears with strange, unreadable marks.

I have tried putting some code in the email.php like:

$message .= “Content-type: text/plain; charset=utf-8” . "
";
or
$message .= “Content-type: text/plain; charset=iso-8859-2” . "
“;
or
Content-Type” content=“text/html; charset=utf-8” />

but non of them worked.

I was reading on the Internet about converting / setting charset in Flash or php (eg. I System.useCodepage=true; iconv etc…) before sending the email but I do not know exactly how it should be done.

I was thinking also that this might be the server problem, which does not support Polish characters… it this possible?

Many thanks for your help!
