U+31F4 "ㇴ" Katakana Letter Small Nu Unicode Character

U+31F4 "ㇴ" Katakana Letter Small Nu is a small-form variant of the standard katakana character ヌ (nu), used primarily in the Japanese writing system to specify pronunciation or to represent a contracted sound within a word. Unlike its full-sized counterpart, this small version is not typically used as a standalone syllable but appears as a specialized diacritic-like element, often in linguistic or phonetic contexts, to indicate a reduced or devoiced vowel in certain compound kana or transliterations of foreign words. It is part of the Katakana Phonetic Extensions block in Unicode, which was introduced to support such nuanced orthographic distinctions in modern Japanese text processing and scholarly work.
