Right to left direction - Page 1

Hey!
I use this cool stuff for 1 year, but right now I need to display some arabic text. After long search I displayed my arabic characters, but with the direction I have problem. How can I make the text to appear from right to left?
I tried to set the rtl property of tcpdf object, but without success.
Help, please!

And if you use text-align:right, doest it help ?

No, unfortunately not. The text should be not simple right aligned, the direction should be transformed. I tried also the dir property, but also does not work.
