ASCII reserves the first 32 code points (numbers 0–31 decimal) and the last one (number 127 decimal) for control characters. These are codes intended to control peripheral devices (such as printers), or to provide meta-information about data streams, such as those stored on magnetic tape. Despite their name, these code points do not represent ...
WISCII was used on the Wang PC (an IBM-PC compatible), as well as the Alliance APC, OIS, and VS systems. The first 126 characters were the same as ASCII (7-bit), but the remaining characters (ASCII 127-255), which consisted mostly of international letter symbols, were used only by Wang systems.

The delete control character (also called DEL or rubout) is the last character in the ASCII repertoire, with the code 127. [1] It is supposed to do nothing and was designed to erase incorrect characters on paper tape. It is denoted as ^? in caret notation and is U+007F in Unicode.
All entries in the ASCII table below code 32 10 (technically the C0 control code set) are of this kind, including CR and LF used to separate lines of text. The code 127 10 is also a control character. [1] [2] Extended ASCII sets defined by ISO 8859 added the codes 128 10 through 159 10 as control characters. This was primarily done so that if ...
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.
The ASCII coding standard defines the original specification for the mapping of the first 0-127 characters. The table is arranged by Unicode code point. Character sets are referred to here by their IANA names in upper case .
