U+FF0F "／" Fullwidth Solidus Unicode Character
Unicode Version 17.0
／
U+FF0F "／" Fullwidth Solidus is a typographic variant of the standard forward slash (solidus) that occupies the same character width as a fullwidth letter or digit, typically used in East Asian scripts such as Chinese, Japanese, and Korean to maintain consistent visual alignment in monospaced or ideographic text. It serves as a punctuation mark or separator in dates, fractions, and file paths when mixed with fullwidth characters, ensuring the glyph harmonizes with the wider, square-shaped CJK characters. Unlike the standard halfwidth slash, this version is encoded in the Unicode block for fullwidth and halfwidth forms and is distinct from both the regular solidus (U+002F) and the similar-looking division slash (U+2215).
