get_permalink vs the_permalink

Question

I am filtering the_permalink to return a custom structure

 function append_query_string($url) {
$url_endpoint = get_permalink();
$url_endpoint = parse_url( $url_endpoint );
$url_endpoint = $url_endpoint['path']; 
return '#!'. $url_endpoint;
 }
 add_filter('the_permalink', 'append_query_string');

the filter above returns

 #!/theme-folder/name-of-article

I need to remove the leading #! form that url and I had tried using get_permalink but I have found that the filter does not filter get_pemalink. I have checked the codex and I cannot find a filter for get_permalink. Do you know of a way to filter it so that it will match the_permalink? I can't use the_permalink because it outputs the information to the screen and breaks layout. I can't seem to assign it to a variable either.

If we look at get_permalink in source, we'll see the various filters applied to this function.

For posts, it's post_link, for custom post types, it's post_type_link, for pages it's page_link, and attachments is attachment_link.
