Slashes stripped in ACF

Until this gets fixed, the only workaround I can see is to intercept the $_POST data and add extra slashes prior to ACF stripping them:

/**
 * @link http://wordpress.stackexchange.com/q/143555/1685
 */
function wpse_143555_acf_add_slashes() {
    if ( ! empty( $_POST['fields'] ) ) {
        foreach ( $_POST['fields'] as $k => $v ) {
            if ( ! is_array( $v ) )
                $_POST['fields'][ $k ] = addslashes( $v );
        }
    }   
}

add_action( 'save_post', 'wpse_143555_acf_add_slashes', 1 );

Currently it’ll only work on text (string) fields, but I could easily change it to work on others too (not sure of the repercussions though).
