C0 and C1 control codes
Control characters, ranging from U+0000 to U+001F (C0) and U+0080 to U+009F (C1) in Unicode
The C0 and C1 control code or control character sets define control codes for use in text by computer systems that use ASCII and derivatives of ASCII. The codes represent additional information about the text, such as the position of a cursor, an instruction to start a new line, or a message that the text has been received.
