Including a javacript URL with a space

I am trying to include this javascript. But the URL path has a space in it. If I leave the space then /mytheme child/ becomes /mythemechild/. I tried adding %20 and looked at the source code and it showed %20. Can this be done with a space in the URL path?

wp_register_script( 'myscript', get_bloginfo('url').'wordpress/wp-content/themes/mytheme%20child/js/myscript.js');

wp_enqueue_script( 'myscript' );
