U+A867 "ꡧ" Phags-Pa Subjoined Letter Wa Unicode Character

U+A867 "ꡧ" Phags-Pa Subjoined Letter Wa is a glyph from the Phags-pa script, a historic writing system created in the 13th century during the Yuan Dynasty of Mongolia under the direction of the Tibetan lama Drogön Chögyal Phagpa to unify writing across the multilingual Mongol Empire. This specific character represents the sound "wa" and is used in a subjoined position, meaning it attaches below other letters to modify pronunciation, typical of the script's vertical and consonant stack structure. It was primarily employed for writing Mongolian, Chinese, Tibetan, and Sanskrit religious and administrative texts, though the script fell out of common use after the Yuan Dynasty ended, making this character a valuable artifact for historical linguistics and paleography.
