I downloaded 2.1.4 and it works correctly. Thank you!

I use Japanese character.
I updated WPP to 2.1.3 from 2.1.0, and my widget is garbled, too.
It works properly with 2.1.0.

I replaced $instance['title'] = htmlspecialchars( stripslashes(strip_tags( $new_instance['title'] )), ENT_QUOTES ); with $instance['title'] = htmlspecialchars( stripslashes(strip_tags( $new_instance['title'] )), ENT_QUOTES, 'UTF-8', FALSE );, but a problem was not settled.
