How can PHP code be modified to exclude recognizing umlauts as special characters?

When working with PHP, umlauts are often recognized as special characters, which can lead to encoding issues. To exclude umlauts from being treated as special characters, you can use the `utf8_decode()` function to convert the string to ISO-8859-1 encoding, where umlauts are represented as regular characters. 

// Example PHP code snippet to exclude recognizing umlauts as special characters
$string_with_umlauts = "Möglichkeit überprüfen";
$normalized_string = utf8_decode($string_with_umlauts);

echo $normalized_string; // Output: Möglichkeit überprüfen
