U+FF7F "ｿ" Halfwidth Katakana Letter So Unicode Character
Unicode Version 17.0
ｿ
U+FF7F "ｿ" Halfwidth Katakana Letter So is a typographic variant of the fullwidth Katakana character ソ, used primarily in legacy computing environments like early Japanese text terminals and fax machines where character width needed to be reduced to fit monospaced grids. This halfwidth form occupies half the typical display width of a fullwidth character, aligning with ASCII characters in width, and is often utilized in Japanese text for compact formatting or compatibility with older software. It represents the syllable "so" in the Katakana script, one of the three main writing systems of Japanese.
