Writing direction Right to Left please make it possible

I download this software I new this software does not support Arabic and Hebrew and right to left Languages.
But unfortunately this software does not support Right to Left writing in the fields and can not select writing direction from Right to Left.
It is useless for Arabic Farsi, Hebrew and all right to left languages to write in text boxes.
I am a little familiar with Xcode and I know it is simple to define the text fileds for both right to left and left to right writing directions.
Cocoa and Xcode has provided this facility for programmers and it is very easy. Just programmer not should prevent from this facility.
Please not prevent from this ability till we can write in the text boxes from right to left.
