U+FF05 "％" Fullwidth Percent Sign Unicode Character

U+FF05 "％" Fullwidth Percent Sign is a typographic variant of the standard percent sign designed to occupy the same width as a CJK (Chinese, Japanese, and Korean) character, which is typically twice the width of a standard Latin character. It is encoded in the Halfwidth and Fullwidth Forms Unicode block and is used in East Asian text settings where proportional spacing is required to maintain visual alignment and readability, such as in vertical writing or alongside fullwidth digits and punctuation. Unlike the regular ASCII percent sign (U+0025), which is halfwidth, this fullwidth version ensures that the symbol matches the monospaced grid of East Asian scripts, avoiding awkward gaps or misalignment in documents and user interfaces.
