U+FF0B "＋" Fullwidth Plus Sign Unicode Character
Unicode Version 17.0
＋
U+FF0B "＋" Fullwidth Plus Sign is a typographic variant of the standard plus sign designed to occupy the same width as a CJK (Chinese, Japanese, and Korean) character, making it harmonize visually within monospaced or East Asian text settings. Its primary use is in mixed writing systems where fullwidth punctuation or symbols are required for alignment and consistency, such as in menus, forms, or tables. It is encoded in the Halfwidth and Fullwidth Forms block of Unicode and is distinct from the regular plus sign (U+002B), as it occupies two bytes in traditional encodings like Shift JIS and provides a symmetrical appearance alongside other fullwidth characters.
