U+D7C5 "ퟅ" Hangul Jungseong Araea-A Unicode Character

U+D7C5 "ퟅ" Hangul Jungseong Araea-A is a rare and obsolete vowel symbol from the Hangul writing system, historically used for the Korean language but no longer present in modern Korean orthography. It represents a medial (jungseong) vowel, specifically the "araea-a" sound, which is generally believed to have been a low or central vowel distinct from the modern "a" and "eo" sounds. This character is part of the Hangul Compatibility Jamo block in Unicode, though it is considered a historical or linguistic artifact rather than a living, productive letter. In contemporary contexts, "ퟅ" is primarily encountered in scholarly studies of Middle Korean phonology or in digital representations of archaic texts, and it does not appear in standard modern Korean keyboards or everyday writing.
