International Standards Organization 646, for encoding information as the International Reference Version from which all other country specific encodings are based (1972 to 1990).
Also known as:
USASCII - X3.4-1967 -- there two notable difference: broken vertical bar instead of vertical bar, international currency symbol instead of dollar sign.
ISO 646-IRV-1991 -- capitalist forces displace ISO 646-IRV-1972 with ISO 646-US-1972, establishing the new International Reference Version of ISO 646-IRV-1991. BFD.
Note: I have not reproduced the entire family of ISO 646 encodings. Only ISO 646-US-1972 / ISO 646-IRV-1992, and ISO 646-IRV-1972. Check out Roman Czyborra's [Good ole' ASCII] for more thorough coverage.
Technical note: ISO 646 focuses on the glyphs and not upon the control codes, whereas ASCII and its successor USASCII comingled the glyphs with the control codes. The control codes are covered by a different specification: ISO 6429. ISO 2022 covers escape sequences, commonly known as ANSI sequences or VT100/VT102 sequences. So, my pardon for comingling the ISO 6429 in with the ISO 646 -- you've got your peanut butter on my chocolate.
Also of note, ISO 10538 is the specification which describes control functions needed for specifying the layout of text. And ISO 8879 specifies SGML.
As per ISO 6429, the newline sequence: 0A (LF)
CP/M and Microsoft DOS and Windows idiosyncratically uses: 0D 0A (CR LF)
Apple's AppleDOS, ProDOS, GS/OS and MacOS idiosyncratically uses: 0D (CR)
Unix, AmigaOS, Linux, and many other OS's use the standard's specification.
