[[Outline font]]s (also known as vector fonts) use drawing instructions or mathematical formulæ to describe each glyph. [[Stroke font]]s use a series of specified lines (for the glyph's border) and additional information to define the ''profile'', or ''size'' and shape of the line in a specific face and size, which together describe the appearance of the glyph.

Fonts also include embedded special [[orthography|orthographic]] rules to output certain combinations of letterforms (an alternative symbols for the same letter) be combined into special [[Ligature (typography)|ligature forms]] (mixed characters). [[Operating system]]s, web browsers ([[user agent]]), and other software that extensively use typography, use a font to display text on the screen or print media, and can be programmed to use those embedded rules. Alternatively, they may use external script-shaping technologies (rendering technology or “[[https://unicodetokrutidev.co.in smart font]]” engine), and they can also be programmed to use either a large Unicode font, or use multiple different fonts for different characters or languages.
