U+A861 "ꡡ" Phags-Pa Letter O Unicode Character

U+A861 "ꡡ" Phags-Pa Letter O is a glyph from the Phags-Pa script, an alphabet created in the 13th century during the Yuan Dynasty in Mongolia and China to unify the writing of the empire's major languages, including Mongolian, Chinese, and Tibetan. This particular character represents the vowel sound "o" and is encoded in the Unicode standard's Phags-Pa block, which was added to support historical and scholarly documentation of the script. The Phags-Pa script, named after its creator the Tibetan monk and state preceptor Drogön Chögyal Phagpa, fell out of common use after the Yuan Dynasty's decline but remains significant for the study of medieval East Asian linguistics and calligraphy.
