Superscript and Subscript
Check these references for other methods to implement superscript/subscript and extra fractions
Fractions
These codes allow fractions to be represented with typographically smaller numerators and denominators, but they can be replaced by other ways of typing a fraction (e.g. "1/2"). CSS Styling can also be used to achieve the same effect as described on Got Unicode and Lars Bruzelius.
Note: The code — means no HTML entity code exists and that a numeric code must be used.

X-Bar, P-Hat and D-Bar
Some codes like that for x̄ (X-bar) are actually a combination of two codes – the base letter x plus a code for the line above (̄: or ̄).
Note: These symbols use combining characters and may not appear correctly in some older browsers.

About The Codes
Using the Entity Codes
The Unicode numeric entity codes can be expressed as either decimal numbers or
hexadecimal numbers.
For instance, the decimal version of the therefore symbol (∴) would be ∴
The hexadecimal version of the therefore symbol (∴) would be ∴
Note that the hexadecimal numbers include x as part of the code.
