U+3165 "ㅥ" Hangul Letter Ssangnieun Unicode Character

U+3165 "ㅥ" Hangul Letter Ssangnieun is a now obsolete consonant used in the Korean writing system, specifically representing a double or tensed version of the alveolar nasal sound "n." This character belongs to a class of complex Hangul letters, known as "ssang" letters, which were historically employed to denote a fortis pronunciation but have since fallen out of modern standard Korean usage. In contemporary Hangul, the sound is instead represented by the regular letter ᄂ (nieun) as the tensed distinction for nasals is no longer recognized in the standard orthography. As a result, U+3165 is primarily used for historical or scholarly transcription of Middle Korean texts and for linguistic documentation rather than in everyday writing.
