The Wikipedia has the following information about this codepoint:

The Ol Chiki (ᱚᱞ ᱪᱤᱠᱤ) script, also known as Ol Chemetʼ (Santali: ol 'writing', chemet' 'learning'), Ol Ciki, Ol, and sometimes as the Santali alphabet invented by Pandit Raghunath Murmu in the year 1925, is the official writing system for Santali, an Austroasiatic language recognized as an official regional language in India. It has 30 letters, the forms of which are intended to evoke natural shapes. The script is written from left to right, and has two forms (Chapa and Usara); the latter form is not Unicoded. In both forms, this alphabet was invented as a unicameral script (in other words, as a script which 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.
