Anything to do with fonts, typography, typeface, etc... Fonts are a set of glyphs or images that represent characters from some particular character set in a particular size and typeface. In computers, a computer font is an electronic data file which contains a set of glyphs, characters, or symbols such as wingdings. Although the term font first referred to a set of metal type sorts in one style and size, since the 1990's most fonts are digital and used for computers or computer devices.
