In computing and telecommunications, a control character or non-printing character (NPC) is a code point in a character set that does not represent a written character or symbol. They are used as in-band signaling to cause effects other than the addition of a symbol to the text.
Non-breaking space (°) is a space character that prevents an automatic line break at its position. Pilcrow (¶) is the symbolic representation of paragraphs. Line break (↵) breaks the current line without new paragraph. It puts lines of text close together. Tab character (→) is used to align text horizontally to the next tab stop.
In a broader sense, other non-printing format characters, such as those used in bidirectional text, are also referred to as control characters by software; [2] these are mostly assigned to the general category Cf (format), used for format effectors introduced and defined by Unicode itself.
HTML and XML provide ways to reference Unicode characters when the characters themselves either cannot or should not be used. A numeric character reference refers to a character by its Universal Character Set/Unicode code point, and a character entity reference refers to a character by a predefined name. A numeric character reference uses the ...
The following table shows the MSX character set. Each character is shown with a potential Unicode equivalent if available. Control characters and other non-printing characters are represented by their names. Character set differences exist, depending on the target market of the machine. These are the variations: Arabic; Brazilian; German DIN ...
Computers excel at automatically typesetting and correcting documents. [7] Character-by-character, computer-aided phototypesetting was, in turn, rapidly rendered obsolete in the 1980s by fully digital systems employing a raster image processor to render an entire page to a single high-resolution digital image , now known as imagesetting.
The output of subsequent characters is typically shifted to the right (or to the left for right-to-left script) or to the start of the next line. The effect of multiple sequential whitespace characters is cumulative such that the next printable character is rendered at a location based on the accumulated effect of preceding whitespace characters.
On many Unix systems and early dial-up bulletin board systems the only common standard for box-drawing characters was the VT100 alternate character set (see also: DEC Special Graphics). The escape sequence Esc ( 0 switched the codes for lower-case ASCII letters to draw this set, and the sequence Esc ( B switched back:
