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. Other superscript letters can be found in the
Spacing Modifier Letters,
Phonetic Extensions and
Phonetic Extensions Supplement blocks, while the superscript 1, 2, and 3, inherited from
ISO 8859-1, were included in the
Latin-1 Supplement block.
