What are the common mistakes or errors that can prevent the successful conversion of umlauts in PHP scripts?

One common mistake that can prevent the successful conversion of umlauts in PHP scripts is not properly setting the character encoding. Make sure to use UTF-8 encoding to handle umlauts correctly. Additionally, ensure that the functions used for converting umlauts, such as `iconv` or `mb_convert_encoding`, are used correctly with the appropriate parameters. 

// Set the character encoding to UTF-8
header('Content-Type: text/html; charset=utf-8');

// Convert umlauts using mb_convert_encoding
$text = "Möglichkeit";
$converted_text = mb_convert_encoding($text, 'UTF-8', 'ISO-8859-1');

echo $converted_text;
