U+1C68 "ᱨ" Ol Chiki Letter Ir Unicode Character

U+1C68 "ᱨ" Ol Chiki Letter Ir is the twenty-seventh letter in the Ol Chiki script, which was created in the early 20th century by Pandit Raghunath Murmu specifically for writing the Santali language, an Austroasiatic language spoken primarily in eastern India. This character represents the sound /ir/ or a close front unrounded vowel with a slight r-coloring, and it plays a crucial role in accurately transcribing Santali phonology, which includes a distinct set of vowels unique to the language. As part of the Ol Chiki block, this letter supports the written tradition of the Santali people and is used in educational materials, literature, and official documents to preserve and promote their linguistic heritage.
