U+FF3C "＼" Fullwidth Reverse Solidus Unicode Character
Unicode Version 17.0
＼
U+FF3C "＼" Fullwidth Reverse Solidus is a typographic variant of the standard ASCII backslash, designed to occupy the same horizontal space as other fullwidth characters in East Asian scripts like Chinese, Japanese, and Korean. It is encoded in the Halfwidth and Fullwidth Forms block and is commonly used in contexts where a monospaced, square-shaped character grid is required, such as in terminal interfaces, plain text tables, or legacy computing environments. While it visually resembles a backslash, its primary function is to provide visual consistency in mixed-script text, where punctuation and symbols must align with the larger width of fullwidth CJK characters.
