The feed widget breaks UTF-8 titles
|Reported by:||nbachiyski||Owned by:||azaozz|
WP_Widget_RSS::widget() calls htmlentities() on the feed title, which by default assumes the string is in iso-8859-1 and thus encodes every byte as an entity.
In fact, we don't need to use htmlentities(), since the title is used in HTML. esc_html() is enough.
