displaying and storing Arabic characters

I have an array that stores it's elements from a text file. I want to store Arabic characters inside that file but i have problems:

1. When I try to write this word in text it display it opposite not correct : ex. شجرة I want to store that word when i paste it in text file it converted into backward direction like tree becomes eert.

2. I don't know anything about Unicode converting to display it in a label?? can any one help me with storing it in array and display it in label???

Thank you.

The new release of Mac OS X 'Lion' is going to provide support for the arabic language system wide. I assume this will fix the problem of editing Arabic characters in Xcode. There is also a support for Arabic with text-to-voice services, a new Arabic 'speaker' or sound called Majed.
