- Graphic character
In
ISO/IEC 646 (commonly known asASCII ) and related standards includingISO 8859 andUnicode , a graphic character is any character intended to be written, printed, or otherwise displayed in a form that can be read by humans. In other words, it is any encoded character that is associated with one or moreglyph s.In ISO 646, graphic characters are contained in rows 2 through 7 of the
code table. However, two of the characters in these rows, namely thespace character SP at row 2 column 0 and the delete character DEL (also called the rubout character) at row 7 column 15, require special mention.The space is considered to be "both" a graphic character and a
control character in ISO 646; this is probably due to it having a visible form oncomputer terminal s but a control function (of moving the print head) onteletypes . In Unicode, space is considered a graphic character.The delete character is strictly a control character, not a graphic character. This is true not only in ISO 646, but also in all related standards including Unicode. However, many modern character sets deviate from ISO 646, and as a result a graphic character might occupy the position originally reserved for the delete character.
