U+FF10 "０" Fullwidth Digit Zero Unicode Character
Unicode Version 17.0
０
U+FF10 "０" Fullwidth Digit Zero is a typographic variant of the standard ASCII digit zero, designed to occupy the same width as a fullwidth letter in East Asian scripts such as Chinese, Japanese, and Korean, where characters traditionally fill a square monospaced space. Unlike the standard digit zero, which can sometimes be confused with the uppercase letter O, this fullwidth version has a distinct, wider appearance and is often used in text that requires visual alignment or consistency with neighboring fullwidth characters, such as in formatted tables, financial documents, or digital interfaces that mix CJK text with numerals.
