a) [ISO] A character, other than a control function, that has a visual representation normally handwritten, printed or displayed. b) [IBM] A graphic symbol such as a numeric, alphabetic, or special character, or ideogram.
A member of a set of symbols that represent data. Graphic characters can be letters, digits, punctuation marks, or other symbols. Synonymous with glyph.
Graphic characters are those assigned pictorial images rather than just names. All the non-Meta (q.v.) characters except for the Control (q.v.) characters are graphic characters. These include letters, digits, punctuation, and spaces; they do not include RET or ESC. In Emacs, typing a graphic character inserts that character (in ordinary editing modes). See section Basic Editing.
