What potential issues can arise when using Umlauts in PHP GET requests?

Potential issues that can arise when using Umlauts in PHP GET requests include encoding problems that may lead to incorrect characters being displayed or processed. To solve this issue, you can use the `urlencode()` function to properly encode the Umlauts before sending the GET request. 

// Encode Umlauts in GET request
$umlaut = "ü";
$encodedUmlaut = urlencode($umlaut);

// Send GET request with encoded Umlaut
$url = "https://example.com/api?umlaut=" . $encodedUmlaut;
$response = file_get_contents($url);

// Decode the response if needed
$decodedResponse = urldecode($response);
