Hewlett-Packard started to add European characters to their extended 7-bit / 8-bit ASCII character set HP Roman Extension around 1978/1979 for use with their workstations, terminals and printers. This later evolved into the widely used regular 8-bit character sets HP Roman-8 and HP Roman-9 (as well as a number of variants).
95 characters; the 52 alphabet characters belong to the Latin script. The remaining 43 belong to the common script. The 33 characters classified as ASCII Punctuation & Symbols are also sometimes referred to as ASCII special characters. Often only these characters (and not other Unicode punctuation) are what is meant when an organization says a ...
Code page 437 (CCSID 437) is the character set of the original IBM PC (personal computer). [2] It is also known as CP437, OEM-US, OEM 437, [3] PC-8, [4] or MS-DOS Latin US. [5] The set includes all printable ASCII characters as well as some accented letters (), Greek letters, icons, and line-drawing symbols.
[3] [4] Microsoft has assigned code page 28592 a.k.a. Windows-28592 to ISO-8859-2 in Windows. IBM assigned code page 912 to ISO 8859-2, [ 5 ] until that code page was extended in 1999. [ 6 ] Code page 1111 is similar, but replaces byte B0 ° (degree sign) with U+02DA ˚ (ring above).
Stanford Extended ASCII (SEASCII) is a derivation of the 7-bit ASCII character set developed at the Stanford Artificial Intelligence Laboratory (SAIL/SU-AI) in the early 1970s. [1] Not all symbols match ASCII.
The phrase ANSI character set has no well-defined meaning and has been used to refer to the following, among other things: . Windows code pages, a collection of 8-bit character sets compatible with ASCII but incompatible with each other, especially those code pages that are partly compatible with ISO-8859, most commonly Windows Latin 1
The Apple Macintosh computer introduced a character encoding called Mac Roman in 1984. It was meant to be suitable for Western European desktop publishing. It is a superset of ASCII, and has most of the characters that are in ISO-8859-1 and all the extra characters from Windows-1252, but in a totally different arrangement.
The WHATWG Encoding Standard, which specifies the character encodings permitted in HTML5 which compliant browsers must support, [12] includes most parts of ISO/IEC 8859, [13] except for parts 1, 9 and 11, which are instead interpreted as Windows-1252, Windows-1254 and Windows-874 respectively. [14]
