U+117F "ᅿ" Hangul Jungseong O-Eo Unicode Character

U+117F "ᅿ" Hangul Jungseong O-Eo is a medieval or archaic vowel symbol used in the Hangul writing system for the Korean language, specifically representing a diphthong that combines the sounds of "o" and "eo." This character is classified under the Hangul Jamo block and is part of the set of obsolete or historical vowels that were present in older forms of Korean orthography but are no longer used in the modern standard alphabet. Its purpose was to phonetically encode a distinct vowel sound that has since merged with other vowels in contemporary speech, making it primarily of interest to linguists, historians, and scholars studying the evolution of the Korean script.
