U+1C66 "ᱦ" Ol Chiki Letter Ih Unicode Character

U+1C66 "ᱦ" Ol Chiki Letter Ih is a symbol from the Ol Chiki script, which was specifically created for writing the Santali language, an Austroasiatic language spoken primarily in eastern India. This character represents the voiced glottal fricative sound /ɦ/, akin to the English "h" in "ahead," and is part of the script's unique set of letters designed to accurately capture Santali phonetics. The Ol Chiki alphabet was developed in the 1920s by Pandit Raghunath Murmu to provide a standardized writing system for Santali, and the letter "Ih" is used in transliterating words with this specific sound, playing a key role in preserving and promoting Santali literature and culture.
