Question

I have the following PHP in my contact form.

// Ensure a message was entered, then sanitize it
if(!empty($_POST['cf_m']) && $_POST['cf_m']!='Enter Your Message Here')
{
    $message = strip_tags($_POST['cf_m']);
}

When I receive a message by email, the Norwegian characters, æ, ø, å become æ, ø, Ã¥.

What can I do in order to show the correct characters?

You must set the encoding in the mail header, like it’s explained in the php-comments on mail() (http://de.php.net/manual/de/function.mail.php):

<?php
function mail_utf8($to, $subject = '(No subject)', $message = '', $from) {
  $header = 'MIME-Version: 1.0' . "\n" . 'Content-type: text/plain; charset=UTF-8'
    . "\n" . 'From: Yourname <' . $from . ">\n";
  mail($to, '=?UTF-8?B?'.base64_encode($subject).'?=', $message, $header);
}
?>
