php - 联系表无法识别 UTF-8 希腊语

Question

我正在处理有关希腊语的问题。当我点击发送按钮时，我在电子邮件中看到的字母就像这样的 åôÜöáóáé。
我已经尝试过:

 1. php: header('Content-type: text/html; charset=utf-8');
    2. html: <meta http-equiv="Content-type" content="text/html; charset=utf-8" />
    3 html: <form role="form" action="contact.php" method="post" accept-charset="UTF-8">

我能做些什么来解决这个问题？谢谢!!!

HTML

    <form role="form" action="contact.php" method="post" > 
    <div class="col-md-4">
    
    <input type="text" name="name" placeholder="Fullname *">
    <input type="text" name="email" placeholder="Email *">
    <input type="text" name="subject" placeholder="Subject*">
    <textarea name="message" placeholder="Message *"></textarea>

    <button type="submit" name="submit" value="Submit"> Send</button>
    </div>
     </form>


PHP
  <?php header("Content-type: text/html; charset=utf-8"); 
    
    $name = $_POST['name'];
    $email = $_POST['email'];
    $subject = $_POST['subject'];
    $message = $_POST['message'];
    
    $formcontent=" Name: $name \n Email: $email \n Subject: $subject \n Message: $message";
    
    $recipient = "support@mydomain.com";
    $subject = "Contact Form";
    $mailheader = "From: $email \r\n";
    
    mail($recipient, $subject, $formcontent, $mailheader) or die("Error!");
    
    ?>

Answer 1

经过大量研究，解决方案是:

HTML:

  <meta charset="UTF-8">

HTML 表格:

 <form action="contact.php" method="POST" accept-charset='UTF-8'>

PHP:
添加到 $mailheader

$mailheader = 'From: '.$email_from."\r\n".
    'Content-Type: text/html; charset=UTF-8' . "\r\n" .
    'Para: WebSite'  .  "\r\n" .
    'X-Mailer: PHP/' . phpversion();

这 100% 有效，现在联系表可以识别希腊语。
