Linguist student Banwang Losu developed an independent Wancho script in order to preserve 'Wancho language' which is spoken in several northeastern states. Wancho is one of the tribes in Arunachal Pradesh which lacked a script.

Losu who was enlisted in the US-based Unicode Consortium for online use said, "It took me almost 12 years to script the Wancho language. It is not only confined to Arunachal Pradesh but is also spoken in Nagaland, Assam and other countries like Myanmar and Bhutan."
