Deprecated: htmlentities(): Passing null to parameter

Error shown on page:

Deprecated: htmlentities(): Passing null to parameter #1 ($string) of type string is deprecated in /var/www/vhosts/tsugi/vendor/tsugi/lib/src/Util/U.php on line 53

PHP 8.1 deprecates these calls, it does not make them errors. The purpose of deprecation is to give authors advance notice to fix their code, so you and the authors of libraries you use have until PHP 9.0 comes out to fix things.

Fix is:

public static function htmlent_utf8($string) { return htmlentities($string ?? '',ENT_QUOTES,$encoding = 'UTF-8'); }
