U+FF75 "ｵ" Halfwidth Katakana Letter O Unicode Character
Unicode Version 17.0
ｵ
U+FF75 "ｵ" Halfwidth Katakana Letter O is a typographic variant of the standard fullwidth katakana character オ, designed specifically for compatibility with legacy computer systems and character encodings such as Shift JIS where characters were often represented in a monospaced grid of half the usual width. This halfwidth form of the katakana syllable "o" takes up a single character cell in width, making it useful for applications where space is limited, such as in terminal displays, old video game text, or when mixing with other halfwidth scripts like Latin letters and digits.
