U+00B9 "¹" Superscript One Unicode Character
Unicode Version 17.0
U+00B9 "¹" Superscript One is a typographic glyph used to denote the numeral one in a superscripted form, primarily found in mathematical expressions, footnotes, and ordinal indicators such as "1st" in some languages. It belongs to the Latin-1 Supplement block and is encoded at code point 00B9 in Unicode, with a standardized HTML entity of `¹`. This character is distinct from the regular digit "1" and is often employed in scientific notation, chemical formulas, or text formatting to represent powers or indices, such as in "m¹" for meter per second or when indicating a footnote reference. Its appearance may vary slightly across fonts but generally appears as a smaller, raised version of the digit one, aligning with other superscript characters like ² and ³.
