 I think it was me that
 [https://core.trac.wordpress.org/ticket/48965#comment:13 highlighted] to
 post title of 'zero' issue, following from conversation about this with
 JoyR.

 In my testing `if ( trim( $post_title ) === '' )` works as expected and
 maintains the strict comparison:

 `$tests = array( 0, NULL, 'foo', '', '0' );
 foreach ( $tests as $test ) {
         if ( '' === trim( $test ) ) {
                 var_dump( $test );
                 echo ' is empty!';
         }
 }`
