Punjab
The major language spoken in the Punjab is Punjabi. In the Indian Punjab this is written in the Gurmukhi script. Pakistan uses the Shahmukhi script, that is closer to Urdu script. Hindi, written in the Devanagri script, is used widely in the Indian states of Himanchal Pradesh and Haryana. Several dialects of Punjabi are spoken in the different regions. The Majhi dialect is considered to be textbook Punjabi and is shared by both countries.
Shahmukhi alphabet
The Shahmukhi alphabet was first used by the Sufi poets of the Punjab; it became the conventional writing style for the Muslim populace of the Pakistani province of Punjab following the independence of Pakistan in 1947, while the largely Hindu and Sikh modern-day state of Punjab, India adopted the Gurmukhi script to record the Punjabi language.
