German mutated vowels (ö,ä,ü, etc) are not displayed correctly in the emails, sent over a html/php contact-form even the the UTF-8 declaration is set.
PHP file:
    <meta http-equiv="Content-Type" content="text/html"; charset="utf-8" />
<?php
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];
    $from = 'From: Website'; 
    $to = 'xxx@gmx.de'; 
    $subject = 'Hi there';
    $human = $_POST['human'];
    $body = "From: $name\n E-Mail: $email\n Message:\n $message";
    if ($_POST['submit']) {
    if ($name != '' && $email != '')
In the html file the utf declaration is set as well:
<!DOCTYPE html>
<meta charset="utf-8">
The special characters looks like this "ü"
