Ol Chiki script

The Ol Chiki (ᱚᱞ ᱪᱤᱠᱤ) script, also known as Ol Chemetʼ (ᱚᱞ ᱪᱮᱢᱮᱫ, ol 'writing', chemetʼ 'learning'), Ol Ciki, Ol, and sometimes as the Santali alphabet is the official writing system for Santali, an Austroasiatic language recognized as an official regional language in India. It was invented by Pandit Raghunath Murmu in 1925. It has 30 letters, the design of which is intended to evoke natural shapes. The script is written from left to right, and has two styles (the print Chapa style and cursive Usara style). Unicode does not maintain a distinction between these two, as is typical for print and cursive variants of a script. In both styles, the script is unicameral (that is, it does not have separate sets of uppercase and lowercase letters).

The shapes of the letters are not arbitrary, but reflect the names for the letters, which are words, usually the names of objects or actions representing conventionalized form in the pictorial shape of the characters.
