largo_post_social_links should respect get_option('blog_charset')

https://github.com/INN/Largo/blob/d94cf0c39643c701fb443253334dc78079f0e8e8/inc/post-tags.php#L247:

            $output .= sprintf(
                $twitter_share,
                // Yes, rawurlencode. Otherwise, the link will break. Use html_entity_decode to handle wordpress saving smart quotes as Ӓ entities.
                rawurlencode( html_entity_decode( get_the_title(), ENT_QUOTES, "UTF-8" ) ),
                rawurlencode( get_permalink() ),
                $via,
                __( 'Tweet', 'largo' )
            );

But we use proper support in https://github.com/INN/Largo/blob/a5a0b7fdaedcfe261023be7e6f642956d51e58b4/inc/widgets/largo-inn-rss.php#L80 :

            $desc = str_replace( array("\n", "\r"), ' ', esc_attr( strip_tags( @html_entity_decode( $item->get_description(), ENT_QUOTES, get_option('blog_charset') ) ) ) );
