NameFullwidth plus sign
Unicode numberU+FF0B
CategoryFullwidth ASCII variants
DescriptionThe Unicode character +, or U+FF0B, is known as the "Fullwidth Plus Sign". It belongs to the "Halfwidth and Fullwidth Forms" block and falls under the "Symbol, Math" category in the Unicode standard. This symbol is a variant of the common plus sign "+" but is designed to take up the same width as a Chinese, Japanese, or Korean character, which is typically wider than the standard plus sign in Latin scripts. It is used in East Asian texts to balance the typography when mixing these scripts with Latin characters. Like the standard plus sign, it denotes addition in mathematical contexts or can indicate a positive quantity.
