Description

The Unicode character ², or U+00B2, is named "Superscript Two". It is part of the "Latin-1 Supplement" block, which extends the original ASCII character set to include additional characters used in Western languages. This character falls under the "Number, Other" category. Visually, it represents the digit two in a smaller font size and positioned slightly above the baseline, which is the typical presentation style for superscript characters. In mathematical and scientific contexts, the superscript two is most commonly used to represent the square of a number or variable (for example, x² means "x squared", or "x times x"). It may also be used in textual contexts to indicate a footnote or reference mark.
