Comment (by andraganescu):

 A quick fix for PHP 8 is to do the array casting before the `foreach`
 loop, in `/wp-includes/class.wp-scripts.php:localize` like:

 {{{
 $l10n = ( array ) $l10n;
 foreach ( $l10n as $key => $value ) {
         if ( ! is_scalar( $value ) ) {
                 continue;
         }

         $l10n[ $key ] = html_entity_decode( (string) $value, ENT_QUOTES,
 'UTF-8' );
 }
 }}}

 But it seems so "hacky" :)
