U+A846 "ꡆ" Phags-Pa Letter Ja is a letter from the Phags-pa script, an alphabet created in the 13th century by the Tibetan monk Drogön Chögyal Phagpa for the Mongolian emperor Kublai Khan to uniformly transcribe multiple languages including Mongolian, Chinese, and Tibetan. This specific character represents the sound "ja" and belongs to the Phags-pa block within the Unicode standard, which was added to support historical and linguistic research into the script's use for official documents, religious texts, and transcriptions during the Yuan dynasty.
