我很难理解如何用WordPress转义翻译的字符串。。。

以下代码来自Wordpress codex：

function wpdocs_kantbtrue_init()
{
    $args = array(
        \'labels\' => array(
            \'name\'                  => _x( \'Recipes\', \'Post type general name\', \'recipe\' ),
            \'singular_name\'         => _x( \'Recipe\', \'Post type singular name\', \'recipe\' ),
            \'menu_name\'             => _x( \'Recipes\', \'Admin Menu text\', \'recipe\' ),
            \'name_admin_bar\'        => _x( \'Recipe\', \'Add New on Toolbar\', \'recipe\' ),
            \'add_new\'               => __( \'Add New\', \'recipe\' ),
            \'add_new_item\'          => __( \'Add New recipe\', \'recipe\' ),
            \'new_item\'              => __( \'New recipe\', \'recipe\' ),
            \'edit_item\'             => __( \'Edit recipe\', \'recipe\' ),

            ... 
        )
    );

    register_post_type(\'Recipe\', $args);
}
add_action(\'init\', \'wpdocs_kantbtrue_init\');

我想我在某个地方读到过，所有的东西都应该转义，我很确定，\\uuu（）函数不会转义任何东西，它只是返回翻译后的文本。。。

我在某处也看到过：

$wp_customize->add_setting(\'address\', array(
    \'default\'           =>  esc_html__(\'Enter your Address in this field\', \'themename\'),
    \'sanitize_callback\' =>  \'sanitize_text_field\',
    \'transport\'         =>  \'postMessage\'
)); 

那么最安全的方法是什么呢？
