How can the issue with Umlauts in a PHP script be resolved?

Issue: The problem with Umlauts in a PHP script can be resolved by ensuring that the PHP file is saved with UTF-8 encoding and using the mbstring functions to properly handle multibyte characters.

// Set UTF-8 encoding
header('Content-Type: text/html; charset=UTF-8');

// Use mbstring functions to handle Umlauts
$text = "Möglichkeit";
$text = mb_convert_encoding($text, 'UTF-8', 'auto');
echo $text;
