What is the potential issue with displaying umlauts in a loop in PHP?

When displaying umlauts in a loop in PHP, the potential issue is that the umlaut characters may not be displayed correctly due to encoding problems. To solve this issue, you can use the `utf8_encode()` function to convert the string to UTF-8 encoding before displaying it. 

foreach ($umlautsArray as $umlaut) {
    echo utf8_encode($umlaut) . "<br>";
}
