Check my free Amiri font (http://amirifont.org), it has full Unicode 6.0 Arabic coverage, with 6.1 additions under the way. But if you are using a layout engine that predates the addition of that character into Unicode, even a good font will not help here since the engine will be using the older Unicode character database where the joining behaviour of this letter is undefined.
