All other characters are mainly graphic characters, also known as printing characters (or printable characters), except perhaps for "space" characters. In the ASCII standard there are 33 control characters, such as code 7, BEL, which rings a terminal bell.
In 1973, ECMA-35 and ISO 2022 [18] attempted to define a method so an 8-bit "extended ASCII" code could be converted to a corresponding 7-bit code, and vice versa. [19] In a 7-bit environment, the Shift Out would change the meaning of the 96 bytes 0x20 through 0x7F [a] [21] (i.e. all but the C0 control codes), to be the characters that an 8-bit environment would print if it used the same code ...
Control Characters: (see File:US ASCII Control Character Symbols.png) Deutsch: US-ASCII Kodierungstabelle (1967). Die ursprüngliche Notation war 4/11 (Spalte/Zeile) für "K", da die Spalten zu je 16 Zeichen (untere 4 Bit) Gruppen darstellen.
ASCII was incorporated into the Unicode (1991) character set as the first 128 symbols, so the 7-bit ASCII characters have the same numeric codes in both sets. This allows UTF-8 to be backward compatible with 7-bit ASCII, as a UTF-8 file containing only ASCII characters is identical to an ASCII file containing the same sequence of characters.
Control Pictures is a Unicode block containing characters for graphically representing the C0 control codes, and other control characters. Its block name in Unicode 1.0 was Pictures for Control Codes .

For example, the character "a" has a binary ASCII code of 110 0001. This code would be converted to 000 0001, corresponding to the ASCII character with id 1 (the SOH Character). The table at C0 and C1 control codes § C0 controls shows the ASCII control characters, with the "Caret notation" column showing a caret (^), followed by the character ...
