Urdu Took 28 Letters From Arabic. Where Did the Other 11 Come From?

Watch on YouTube

About this piece

Urdu is written with 39 letters of the Arabic alphabet. 28 came from Arabic. A viewer asked about the other 11, and about their Unicode numbers.

پ is ب with 2 more dots. ٹ is ت with a tiny ط on top. ں is ن with its dot taken away. Not one of the 11 is a brand new shape.

In Unicode, 26 of the 39 sit in Arabic's own row and 13 live far down the block, so sorting by number scrambles the dictionary. ک and ك can look exactly the same and still be different text, so a search walks right past one of them. And in the Urdu hand, every word hangs downhill, one letter sitting on the next one's shoulder.
