U+FF08 "(" Fullwidth Left Parenthesis Unicode Character

Unicode Version 17.0

U+FF08 "(" Fullwidth Left Parenthesis is a typographic variant of the standard left parenthesis, designed to occupy the same width and visual space as other fullwidth CJK (Chinese, Japanese, and Korean) characters, making it appear square and proportional within East Asian text layouts. It belongs to the Halfwidth and Fullwidth Forms block and is commonly used in logographic writing systems where characters are monospaced, such as in Japanese, Chinese, and Korean documents, to ensure consistent alignment and readability when mixing punctuation with ideographic text. This character mirrors the function of its halfwidth counterpart but is distinguished by its greater horizontal space and alignment with the em square, often employed in formal writing, digital typography, and legacy character encoding systems like Shift JIS.
