From Wikipedia, the free encyclopedia

Unicode has subscripted and superscripted versions of a number of characters including a full set of arabic numerals. These characters allow any polynomial equation and some other equations to be represented in plain text without using any form of markup like HTML or T_EX. It is considered inadvisable to use these characters when other methods of superscript and subscript are available.

The most common superscript digits were in ISO-8859-1 at positions B9_HEX, B2_HEX and B3_HEX for digits 1, 2, and 3 respectively and have therefore been carried over into those positions in the Latin-1 range of Unicode. The rest were placed in a dedicated section of Unicode at U+2070 to U+209F. The two tables below show the characters in this range. Each superscript or subscript character is preceded by a normal x to show the subscripting/superscripting. The table on the left contains the actual Unicode characters (which may not render correctly in your browser); the one on the right contains the equivalents using HTML markup for the subscript/superscript.
