How can PHP handle Umlauts received via GET requests?

When receiving Umlauts via GET requests in PHP, it's important to properly handle encoding to ensure the characters are correctly interpreted. One way to handle this is by using the `urldecode()` function to decode the URL-encoded characters. This function will convert any `%XX` sequences back into their original characters, including Umlauts. 

// Retrieve the GET parameter containing Umlauts
$umlautString = $_GET['umlauts'];

// Decode the URL-encoded Umlauts
$decodedString = urldecode($umlautString);

// Now $decodedString contains the Umlauts in their original form
