Unicode subscripts and superscripts
unicode has a full set of arabic numberals in subscript and superscript. it also has a few other charactors subscripted or superscripted. Such charactors are usefull when trying to write out say a polynomial equation in plain text without using any form of markup like html or tex.
The most common superscript digits were in iso-8859-1 at positions B9HEX, B2HEX and B3HEX for digits 1 2 and 3 respectively and have therefore been carried over into those positions in the latin1 range of unicode. The rest was placed in a dedicated section of unicde at U+xxxx2070 to U+209F. a table of theese is given below (not all charactors my render in all browsers, red cells are unassigned.
