Are there any best practices or recommended approaches for handling umlauts in PHP text manipulation and display?

When handling umlauts in PHP text manipulation and display, it is recommended to use UTF-8 encoding to ensure proper handling of special characters. You can use functions like mb_convert_encoding() or utf8_encode() to convert strings to UTF-8 encoding before manipulating or displaying them.

// Convert string to UTF-8 encoding
$text = "Möglichkeiten";
$text_utf8 = mb_convert_encoding($text, 'UTF-8', 'ISO-8859-1');

// Display the UTF-8 encoded string
echo $text_utf8;
