U+A871 "ꡱ" Phags-Pa Subjoined Letter Ra Unicode Character

U+A871 "ꡱ" Phags-Pa Subjoined Letter Ra is a glyph from the Phags-pa script, an abugida created in the 13th century during the Yuan dynasty for writing Mongolian, Chinese, and other languages of the empire. This specific subjoined form represents the consonant "ra" when used as a medial or final element in a syllable, attaching below the main character rather than standing alone. It was part of the script's systematic adaptation to represent the sounds of multiple languages, particularly in transliterating Tibetan and Sanskrit texts. The Phags-pa script is now largely historical, and this subjoined letter is primarily of interest to scholars studying medieval Central Asian linguistics, epigraphy, or the development of writing systems.
