U+318E "ㆎ" Hangul Letter Araeae Unicode Character

U+318E "ㆎ" Hangul Letter Araeae is a rarely used vowel symbol from the Korean writing system Hangeul, representing a distinct historical vowel sound that no longer exists in modern standard Korean. This character was used during the Middle Korean period and is often associated with phonetics that have since merged into other vowels, such as "ㅏ" (a) or "ㅡ" (eu). In modern contexts, it is employed primarily for linguistic reconstruction, historical documentation, or in the study of Korean dialects where the sound may still be preserved.
