The C0 and '''C1''' Control Code sets define control codes for use in text. C0, originally defined in ISO 646 , defines codes in the range 00 HEX –1FHEX. C1, originally defined in ISO 6429 , defines codes in the range 80HEX–9FHEX. The C0 codes are contained in ASCII and most encodings based on it. The C1 codes were included in the ISO-8859-n series of encodings and Unicode but are rarely used. When they turn up in documents, Web pages, e-mail messages, etc., which are ostensibly in an ISO-8859-n encoding, their code positions were reused to refer to the characters at that position in a proprietary, system-specific encoding such as Windows-1252 or the Apple Macintosh (" MacRoman ") character set. Most applications only interpret the C0 control codes for LF, CR, and HT. A few applications also interpret C0 codes VT and FF, and the C1 code NEL. Very few applications interpret the other C0 and C1 control codes. __TOC__ C0 (ASCII AND DERIVATIVES) <SPAN ID="C1"></SPAN>C1 (ISO-8859 AND UNICODE) REFERENCES
