No single "Unicode font" includes all the characters defined in the present revision of ISO 10646 (Unicode) standard, as it is continually adding more & more languages and characters. Operating System or Web-Browser (aka, User Agent) or both, which uses a font to display text on the screen or print media, can be programmed to use those embedded rules, or use external script-shaping technologies (also known as Rendering Technology or Smartfont Engine), and they can also be programmed to use either a large unicode font, or use multiple different fonts for different characters or languages. Fonts also includes embedded special orthographic rules to output certain combinations of letterforms (an alternative symbols for the same letter) be combined into special ligature forms (mixed characters). Many fonts have kerning pairs which implements better spacing in between the characters.

Stroke fonts 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. Outline fonts (also known as Vector fonts) use drawing instructions or mathematical formulæ to describe each glyph. A Bitmap font contains a grid of dots known as pixels forming an image of each glyph in each face and size. If a font is chosen which does not contain a glyph for a codepoint used in the document, typically a question mark ("?"), a box, or some other Substitute character is displayed.Ĭomputer fonts use various techniques to display characters or glyphs. The choice of font, which governs how the abstract UCS characters are converted into a bitmap or vector output that can be viewed on a screen or printed, is left up to the user. Rather, it defines the abstract characters as a specific number (known as a codepoint) and also defines the required changes of shape depending on the context the glyph is used in (e.g., Combining characters, precomposed characters and letter- diacritic combinations).
The Unicode standard does not specify or create the font ( typeface), a collection of graphical shapes called glyphs, itself.
