U+00B2 Superscript Two

U+00B2 was added in Unicode version 1.1 in 1993. It belongs to the block U+0080 to U+00FF Latin-1 Supplement in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Other Number and is commonly used, that is, in no specific script. The codepoint represents the digit 2. The character is also known as squared.

The glyph is a superscript version of the glyph Glyph for U+0032 Digit Two. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it is written as European number from left to right. When changing direction it is not mirrored. If its East Asian Width is “narrow”, U+00B2 forms a word with similar characters, which prevents a line break inside it. Otherwise it allows line breaks around it, except in some numeric contexts.

The CLDR project calls this character “superscript two” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: squared, superscript, two.

The Wikipedia has the following information about this codepoint:

In mathematics, a square is the result of multiplying a number by itself. The verb "to square" is used to denote this operation. Squaring is the same as raising to the power 2, and is denoted by a superscript 2; for instance, the square of 3 may be written as 32, which is the number 9. In some cases when superscripts are not available, as for instance in programming languages or plain text files, the notations x^2 (caret) or x**2 may be used in place of x2. The adjective which corresponds to squaring is quadratic.

The square of an integer may also be called a square number or a perfect square. In algebra, the operation of squaring is often generalized to polynomials, other expressions, or values in systems of mathematical values other than the numbers. For instance, the square of the linear polynomial x + 1 is the quadratic polynomial (x + 1)2 = x2 + 2x + 1.

One of the important properties of squaring, for numbers as well as in many other mathematical systems, is that (for all numbers x), the square of x is the same as the square of its additive inverse x. That is, the square function satisfies the identity x2 = (−x)2. This can also be expressed by saying that the square function is an even function.
