The script used to publish Brahma now is called "Brahma", which is based on the naga font produced in China and India in the 7th century and developed into a font suitable for writing in the 11th century. In fact, there are many kinds of ancient Indian scripts, and all scripts derived from Sanskrit letters or Brahmilipi (Brahmilipi letters), such as Siddhartha, can be called Sanskrit.

There have been many legends about Sanskrit creators since ancient times. Volume II of Tang Xuanzang's Records of the Western Regions of the Tang Dynasty says: "Detailed characters, written by Brahma, original vertical rules, 47 characters" (47 letters). "The Vatican Emperor writes at any time, and different immortals make their own words." According to the materials unearthed in Harappa and Mohenjodaro in the modern Indus Valley, the oldest writing used in India is the hieroglyphics in prehistoric times. However, the system of its origin is still inconclusive. Sanskrit and Phoenician writing (the prototype of modern European writing) belong to Semitic writing system, which has been recognized by modern academic circles. Around 700 BC, Indian businessmen contacted people in Mesopotamia (a branch of Semitic people) and sent 22 letters from Semitic people to India. After finishing by Indians, about 400 BC, about 40 letters were finally produced. With the different time and place, calligraphy and fonts are gradually different. Around the first century, Sanskrit in the north gradually became a square font, and Sanskrit in the south gradually became a round font. By the fourth century, the difference between the two was extremely obvious. Among them, Gupta font was developed in the north from the 4th century to the 5th century, and Siddhartha letters were derived from Gupta font in the 6th century. Siddhartha letters were later introduced to China and Japan, and Gupta characters were also circulated in Qiuci and Khotan, forming special letters, which were adopted by various ancient languages in Central Asia.
