How can Umlaut characters be properly displayed in the label of a form submit button in PHP?

To properly display Umlaut characters in the label of a form submit button in PHP, you need to ensure that the PHP file is saved with the correct character encoding (UTF-8) and that the HTML document also specifies UTF-8 encoding. Additionally, you can use HTML entities or UTF-8 characters directly in the button label to display Umlaut characters correctly. 

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<form method="post" action="">
<button type="submit">Submit with Umlaut: Ü or Ü</button>
</form>
</body>
</html>
