dacosta_rafael on "some of post deletes upon saving"

I have the following filter but when I save the post some of the post content gets deleted. Is there an alternate solution?

function filter_post_data( $data, $postarr ){

$content = $data['post_content'];
$title = $data['post_title'];
    $search = array(chr(145),
                    chr(146),
					chr(147),
					chr(148),
					chr(150),
					chr(151)
					);

    $replace = array("'",
                     "'",
					 "'",
					 "'",
					 "-",
					 "-"
					 );
 	$contentSanitized = str_replace($search, $replace, $content);
	$titleSanitized = str_replace($search, $replace, $title);
	$data['post_content'] = $contentSanitized;
	$data['post_title'] = $titleSanitized;
//print_r($data);
	return $data;
}
add_filter( 'wp_insert_post_data' , 'filter_post_data' , '99', 2 );
