Description

The Unicode character ¹, or U+00B9, is named "Superscript One". It belongs to the "Latin-1 Supplement" block, which contains characters used commonly in Western languages and extends the original ASCII character set. The character falls under the "Number, Other" category. Visually, it represents the digit one positioned slightly above the baseline and in a smaller font size, the conventional style for superscript characters. The superscript one is frequently used in mathematical and scientific notation. For example, it can be used to indicate a power or exponent, as in x¹, which simply means "x to the power of one". Furthermore, it can be used in footnotes and other forms of annotations to indicate a reference or note. The specific interpretation of this character can vary depending on context.
