PHP Contact form input doesnt support diacritics

[mikestechs]

I have small problem with my php contact form code. 
I have my site using diacritics which does work perfectly. But my contact form input after submitting looks like this "ÄÅ¡Å" after using any [0-9] keys for diacritics. 

PHP file: 

    <?php
    
    
    $name = $_POST['name'];
    $email = $_POST['email'];
    $phone = $_POST['phone'];
    $service = $_POST['service'];      
    $message = $_POST['message'];      
    
    $from = $name; 
    $to = 'info@email.com'; 
    $subject = "$name - $service";
     
    $body = "Jméno zákazníka: $name\nE-Mail zákazníka: $email\nTelefonní číslo: $phone\nservice: $service\nZpráva: $message ";
    
    if (mail ($to, $subject, $body, $from, $headers)) {
    $headers = array("Content-Type: text/html; charset=UTF-8");
        } 
        else {
            echo "Failed";
        }
    
    
    ?>

Output after submitting the contact form: 

 

  First Last Name
    
    Jméno zákazníka: Name
    E-Mail zákazníka: email
    Telefonní císlo: phone number
    service: havárii
    Zpráva: Ä�Å¡Å�

the "headers" as name, email, phone, service, message is written with diacritics BUT then the input for example here: Zpráva: ÄÅ¡Å is not supported for some reason.

Also the html file include 

 

   <meta charset="utf-8">

Using utf8_encode might work:

utf8_encode($text)

You should also check that the default charset is UTF-8 with phpinfo().
