Arwi used from the eighth to the nineteenth century was popular among Tamil-speaking Muslims. It facilitated the exchange of ideas between Arab and Tamil cultures by the twentieth century Arwi declined. This book analyzes the Computational Study of Arwi focusing on its Encoding particularly in the context of Unicode including specific Arabic and Arwi letters vowels and symbols enable proper representation and encoding of Arwi script for digital applications and text processing.
