U+317F "ㅿ" Hangul Letter Pansios Unicode Character

U+317F "ㅿ" Hangul Letter Pansios is a rarely used glyph from the historical Korean alphabet, representing a sound known as the "pansios" or "half-s" that disappeared from standard modern Korean. This letter was part of the original Hunminjeongeum, the 15th century script created by King Sejong, and it denoted a voiceless alveolar fricative, similar to the English "s" but pronounced with a slightly different tongue placement or a light, breathy quality. Today, ㅿ is obsolete in contemporary Hangul, having merged into the sound of the regular siot (ㅅ), and it appears primarily in historical texts, linguistic reconstructions, or as a curiosity for those studying the evolution of the Korean writing system.
