What script does Languages in Pakistan use?

[TMA]

The only thing left in this country uniting us is this language and now here are the posts in this thread.
Urdu was and is the language of muslims of sub-continent as a symbol of unity and brotherhood, it is not the property of urdu-speakers.
And to that racist fellow i suggest you should better throw us (urdu-speakers) in the arabian sea then you will be happy i guess.

The same could be said of Dari however you are right, we have lost Persian and Urdu remains.
