Thank you guys, the main problem was I am using an arabic font name ” GE family ” which doesn’t have english number and client need to show the digits in english instead of arabic , so i set up a class file in GREP style to convert all the digit to english using english font which automatically changed the RTL direction to LTR so the percentage symbol flipped and became like english, where as the client need the percentage to be RTL.

But i found a better solution, i changed the digit style to an arabic font which had english numeric and did the job :)

Thank you guys for your help :)
