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

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.
