What are the potential pitfalls of using Umlaut characters in PHP autocomplete features?

Using Umlaut characters in PHP autocomplete features can lead to inconsistencies and errors, as some autocomplete libraries may not handle special characters properly. To avoid potential pitfalls, it's recommended to normalize the input by converting Umlaut characters to their standard ASCII equivalents before using them in autocomplete functionality. 

$input = "Möller";
$normalized_input = iconv('UTF-8', 'ASCII//TRANSLIT', $input);
// Use $normalized_input in autocomplete functionality
