U+1B164 "𛅤" Katakana Letter Small Wi Unicode Character

U+1B164 "𛅤" Katakana Letter Small Wi is a typographic variant of the standard katakana character for "wi" (usually ヰ), and it belongs to the Katakana Letter Small block, a relatively recent addition to the Unicode standard used for representing obsolete or historical Japanese phonemes in a smaller, subscript-like form. This small character was historically used in older Japanese orthography to indicate a reduced or less prominent pronunciation of the syllable "wi," often in compound or contracted sounds, and it is now primarily encountered in scholarly texts, linguistic reconstructions, or digital renditions of classical literature.
