Example of subscript and superscript. In each example the first "2" is professionally designed, and is included as part of the glyph set; the second "2" is a manual approximation using a small version of the standard "2". The visual weight of the first "2" matches the other characters better.
The most common superscript digits (1, 2, and 3) were included in ISO-8859-1 and were therefore carried over into those code points in the Latin-1 range of Unicode. The remainder were placed along with basic arithmetical symbols, and later some Latin subscripts, in a dedicated block at U+2070 to U+209F.
Superscripts and Subscripts is a Unicode block containing superscript and subscript numerals, mathematical operators, and letters used in mathematics and phonetics. The use of subscripts and superscripts in Unicode allows any polynomial, chemical and certain other equations to be represented in plain text without using any form of markup like HTML or TeX.
HTML and XML provide ways to reference Unicode characters when the characters themselves either cannot or should not be used. A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name.

The subscripts and superscripts are set in upright font, in keeping with normal practice for numerals and descriptive subscripts. To set the superscript or subscript in oblique font, as for a subscript that itself is a variable, use the HTML <var>...</var> or <i>...</i> tags, or the wikimarkup for italics (''). Note that to get only a ...
The Unicode Consortium and the ISO/IEC JTC 1/SC 2/WG 2 jointly collaborate on the list of the characters in the Universal Coded Character Set.The Universal Coded Character Set, most commonly called the Universal Character Set (abbr. UCS, official designation: ISO/IEC 10646), is an international standard to map characters, discrete symbols used in natural language, mathematics, music, and other ...
The International Phonetic Alphabet uses the superscript n ⁿ for nasal release, the superscript w ʷ to indicate labialized or labio-velarized consonants, the superscript h ʰ for aspirated consonants, the superscript j ʲ for palatalized consonants, the superscript gamma ᵞ for velarized consonants, the superscript turned h ᶣ for labio ...
