Generally, an escape character is not a particular case of (device) control characters, nor vice versa.If we define control characters as non-graphic, or as having a special meaning for an output device (e.g. printer or text terminal) then any escape character for this device is a control one.
They start with a backslash \ and then have a name consisting of letters only. Command names are terminated by a space, a number or any other "non-letter" character. They consist of a backslash \ and exactly one non-letter. Some commands need an argument, which has to be given between curly braces {} after the command name.
In C and many derivative programming languages, a string escape sequence is a series of two or more characters, starting with a backslash \. [3]Note that in C a backslash immediately followed by a newline does not constitute an escape sequence, but splices physical source lines into logical ones in the second translation phase, whereas string escape sequences are converted in the fifth ...
In computer science, an illegal character is a character that is not allowed by a certain programming language, protocol, or program. [1] To avoid illegal characters, some languages may use an escape character which is a backslash followed by another character.
The intended use [2] when these characters were added to Unicode was to produce true superscripts and subscripts so that chemical and algebraic formulas could be written without markup. Thus "H₂O" (using a subscript 2 character) is supposed to be identical to "H 2 O" (with subscript markup).
The backslash \ is a mark used mainly in computing and mathematics. It is the mirror image of the common slash /. It is a relatively recent mark, first documented in the 1930s. It is sometimes called a hack, whack, escape (from C/UNIX), reverse slash, slosh, downwhack, backslant, backwhack, bash, reverse slant, reverse solidus, and reversed ...
An escape sequence changes how the compiler interprets character data in a literal. For example, \n does not represent a backslash followed by the letter n. The backslash escapes the compiler's normal, literal way of interpreting character data. After a backslash, the compiler expects subsequent characters to complete one of the defined escape ...
The UK/Ireland keyboard has both symbols engraved: the broken bar is given as an alternate graphic on the "grave" key; the solid bar is on the backslash key. The broken bar character can be typed (depending on the layout) as AltGr+` or AltGr+6 or AltGr+⇧ Shift+\ on Windows and Compose!^ on Linux. It can be inserted into HTML as ¦ The ...
