U+1C63 "ᱣ" Ol Chiki Letter Aaw Unicode Character

U+1C63 "ᱣ" Ol Chiki Letter Aaw is a vowel character used in the Ol Chiki script, which was created in the 20th century by Pandit Raghunath Murmu for writing the Santali language, an Austroasiatic language spoken primarily in parts of India, Bangladesh, and Nepal. This letter represents the long vowel sound /aː/ and is classified as a complex vowel character within the script, distinguished from the short vowel counterpart by its diacritical marking.
