How can Umlauts be handled in PHP arrays keys?

Umlauts in PHP array keys can be handled by using UTF-8 encoding and ensuring that the array keys are properly encoded. One way to handle this is by using the `mb_convert_encoding()` function to convert the Umlauts to their UTF-8 representation before using them as keys in the array. 

<?php
// Example array with Umlauts in keys
$array = array(
    'Müller' => 'John',
    'Schön' => 'Anna'
);

// Function to convert Umlauts to UTF-8 encoding
function convertUmlauts($string) {
    return mb_convert_encoding($string, 'UTF-8', 'ISO-8859-1');
}

// Convert Umlauts in array keys to UTF-8
$array = array_combine(array_map('convertUmlauts', array_keys($array)), $array);

// Output the updated array
print_r($array);
?>
