    Example migrated from Codex:

    The example below uses the hook content_save_pre to remove undesirable carriage return character.

    add_filter( 'content_save_pre' , 'my_sanitize_content' , 10, 1);
    
    function my_sanitize_content( $content ) {
    
        return str_replace( "\r<figcaption>", "<figcaption>", $content );
    
    }
