Joomla Empty Character

I'd like to know if there's a character that appears invisible in the frontpage of our website but Joomla recognizes it.

I ask this because, many of you know, that you always have to write something in a brief description, but you want it to have nothing on the frontpage so it can look better. Hence why I'm asking if there's such开发者_如何学运维 char.
