Hello, i would appreciate ur help once more. I have created a Form and so far everything works fine but in the emails from the form the umlaut vowels are all messed up and unreadable. Do you have an idea how i could solve this problem? i tried a suggestion i read on the forum on handling scandinavian numbers but it doesn't seem to work, or i am probably not implementing it properly.
Secondly the message(nachricht) just appears in a block without seeming to respect the line breaks i put.
Do you know how i could make my data appear more presentable?

Thank you very much (below is my process.php field)

<?php
$where_form_is="http://".$_SERVER['SERVER_NAME'].strrev(strstr(strrev($_SERVER['PHP_SELF']),"/"));
session_start();
$debug=0;
if( ($_SESSION['security_code']==$_POST['security_code']) && (!empty($_POST['security_code'])) ) {
// Checkbox handling
$field_5_opts = $_POST['field_5'][0];
if($field_5_opts){
$to="vibanterence@yahoo.com;".$_POST['field_3'];
} else{
$to="vibanterence@yahoo.com";
}
mail($to, $_POST['field_2'] ,"Form data: $_POST['field_4']\nContent-Type: text/html; charset=UTF-8: 
Name/Vorname: " . $_POST['field_1'] . "
Betreff: " . $_POST['field_2'] . "
Email: " . $_POST['field_3'] . "
Ihre Nachricht: " . $_POST['field_4'] . "
");
if($debug){
echo "<li>Mailing to: ".to."<br>";
echo "<li>Name/Vorname: ".$_POST['field_1']."<br>";
echo "<li>Betreff: ".$_POST['field_2']."<br>";
echo "<li>Email: ".$_POST['field_3']."<br>";
echo "<li>Nachricht: ".$_POST['field_4']."<br>";
echo "<li>Option: ".$field_5_opts."<br>";
} else {
include("confirm.html");
}
}
else {
echo "Invalid Captcha String.";
}
?>
