			/*
			 * The WooCommerce developers changed the `get_cancel_order_url` function in version 2.1.0.
			 * In version 2.1.0 the WooCommerce plugin uses the `wp_nonce_url` function. This WordPress
			 * function uses the WordPress `esc_html` function. The `esc_html` function converts specials
			 * characters to HTML entities. This is causing redirecting issues, so we decode these back
			 * with the `wp_specialchars_decode` function.
