Line 9:

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 “[[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.

No single "Unicode font" includes all the characters defined in the present [[The Unicode Standard#Unicode revision historyHistory|revision]] of [[Universal Character Set|ISO 10646]] (Unicode) standard, as more and more languages and characters

are continually added to it, and common font formats cannot contain more than 65,535 glyphs (about half the number of characters encoded in Unicode). As a result, font developers and foundries incorporate new characters in newer versions or revisions of a font, or in separate auxiliary fonts intended specifically for particular languages.
