Dear Janet

http://en.wikipedia.org/wiki/Subscript_and_superscript

Do you feel the Subscript and Superscript can also be used accepting negative numbers, fractional numbers, decimal numbers, complex numbers, trigonometric values, logarithm, antilog, Unicode characters etc other than Whole numbers (Integers) in future applications viz Typography, Chemistry, Physics etc

Examples : -3, 2/3, 3.14, −3.5 + 2i, Sin 30, log 100, antilog 2, © (Copyright sign) etc

i.e. Superscripts and Subscript accepting other numbers, characters other than whole numbers.

Awaiting your reply,

Thanks & Regards,

Prashant S Akerkar

Dear Prashant,

Unicode already contains a limited number of super- and subscript characters that are not integers. The list can certainly be extended, but I think it impractical to use such characters in interactive software. Most users would have to cut-and-paste them into the application. (I am able to TYPE many of these characters on my iMac, but only because I learned how to re-program my keyboard. On any other computer, I have to cut-and-paste.)

Another problem is the limitation of computer monitors. Not all computer monitors can display these characters. For example, in the quoted passage below, eight of the characters are unreadable on my system. Sometimes I email equations, only to learn that the recipient cannot read the math symbols. In such situations, I resubmit the equation as a graphic image instead of Unicode text.

"Consolidated for cut-and-pasting purposes, the Unicode standard defines complete sub- and super-scripts for numbers and common mathematical symbols ( ⁰ ¹ ² ³ ⁴ ⁵ ⁶ ⁷ ⁸ ⁹ ⁺ ⁻ ⁼ ⁽ ⁾ ₀ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉ ₊ ₋ ₌ ₍ ₎ ), a full superscript Latin lowercase alphabet except q ( ᵃ ᵇ ᶜ ᵈ ᵉ ᶠ ᵍ ʰ ⁱ ʲ ᵏ ˡ ᵐ ⁿ ᵒ ᵖ ʳ ˢ ᵗ ᵘ ᵛ ʷ ˣ ʸ ᶻ ), a limited uppercase Latin alphabet ( ᴬ ᴮ ᴰ ᴱ ᴳ ᴴ ᴵ ᴶ ᴷ ᴸ ᴹ ᴺ ᴼ ᴾ ᴿ ᵀ ᵁ ⱽ ᵂ ), a few subscripted lowercase letters ( ₐ ₑ ₕ ᵢ ⱼ ₖ ₗ ₘ ₙ ₒ ₚ ᵣ ₛ ₜ ᵤ ᵥ ₓ ), and some Greek letters ( ᵅ ᵝ ᵞ ᵟ ᵋ ᶿ ᶥ ᶲ ᵠ ᵡ ᵦ ᵧ ᵨ ᵩ ᵪ ). Note that since these glyphs come from different ranges, they may not be of the same size and position, depending on the typeface."
