In computing, a code page is a character encoding and as such it is a specific association of a set of printable characters and control characters with unique numbers. Typically each number represents the binary value in a single byte.
Windows-1252 or CP-1252 is a single-byte character encoding of the Latin alphabet that was used by default in Microsoft Windows for English and many Romance and Germanic languages including Spanish, Portuguese, French, and German. This character-encoding scheme is used throughout the Americas, Western Europe, Oceania, and much of Africa.
ISO/IEC 8859-11:2001, Information technology — 8-bit single-byte coded graphic character sets — Part 11: Latin/Thai alphabet, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 2001. It is informally referred to as Latin/Thai. It is nearly identical to the national Thai standard TIS-620 (1990). The sole difference is that ISO/IEC 8859-11 allocates non-breaking space to code 0xA0, while TIS-620 leaves it undefined.
ISO/IEC 8859-6:1999, Information technology — 8-bit single-byte coded graphic character sets — Part 6: Latin/Arabic alphabet, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1987. It is informally referred to as Latin/Arabic. It was designed to cover Arabic. Only nominal letters are encoded, no preshaped forms of the letters, so shaping processing is required for display. It does not include the extra letters needed to write most Arabic-script languages other than Arabic itself.
Code page 855 is a code page used under DOS to write Cyrillic script.
Code page 866 is a code page used under DOS and OS/2 in Russia to write Cyrillic script. It is based on the "alternative code page" developed in 1984 in IHNA AS USSR and published in 1986 by a research group at the Academy of Science of the USSR. The code page was widely used during the DOS era because it preserves all of the pseudographic symbols of code page 437 and maintains alphabetic order of Cyrillic letters. Initially this encoding was only available in the Russian version of MS-DOS 4.01 (1990), but with MS-DOS 6.22 it became available in any language version.
Code page 852 is a code page used under DOS to write Central European languages that use Latin script.
Code page 860 is a code page used under DOS in Portugal to write Portuguese and it is also suitable to write Spanish and Italian. In Brazil, however, the most widespread codepage – and that which DOS in Brazilian Portuguese used by default – was code page 850.
Code page 857 is a code page used under DOS in Turkey to write Turkish.
Several 8-bit character sets (encodings) were designed for binary representation of common Western European languages, which use the Latin alphabet, a few additional letters and ones with precomposed diacritics, some punctuation, and various symbols. These character sets also happen to support many other languages such as Malay, Swahili, and Classical Latin.
Windows code pages are sets of characters or code pages used in Microsoft Windows from the 1980s and 1990s. Windows code pages were gradually superseded when Unicode was implemented in Windows, although they are still supported both within Windows and other platforms, and still apply when Alt code shortcuts are used.
Code page 862 is a code page used under DOS in Israel for Hebrew.
Code page 775 is a code page used under DOS to write the Estonian, Lithuanian and Latvian languages. In Lithuania, this code page is standardised as LST 1590-1, alongside the related Code page 778.
In computing, a hardware code page (HWCP) refers to a code page supported natively by a hardware device such as a display adapter or printer. The glyphs to present the characters are stored in the alphanumeric character generator's resident read-only memory and are thus not user-changeable. They are available for use by the system without having to load any font definitions into the device first. Startup messages issued by a PC's System BIOS or displayed by an operating system before initializing its own code page switching logic and font management and before switching to graphics mode are displayed in a computer's default hardware code page.
Code page 912 is a code page used under IBM AIX and DOS to write the Albanian, Bosnian, Croatian, Czech, English, German, Hungarian, Polish, Romanian, Serbian, Slovak, and Slovene languages. It is an extension of ISO/IEC 8859-2.
Code page 915 is a code page used under IBM AIX and DOS to write the Bulgarian, Belarusian, Russian, Serbian and Macedonian but was never widely used. It would also have been usable for Ukrainian in the Soviet Union from 1933–1990, but it is missing the Ukrainian letter ge, ґ, which is required in Ukrainian orthography before and since, and during that period outside Soviet Ukraine. As a result, IBM created Code page 1124. It is an extension of ISO/IEC 8859-5.
Code page 856, is a code page used under DOS for Hebrew in Israel.
Code page 859 is a code page used under DOS to write Western European languages. It contains all of the characters in ISO 8859-15.
Code page 921 is a code page used under IBM AIX and DOS to write the Estonian, Latvian, and Lithuanian languages. It is an extension of ISO/IEC 8859-13.
Code page 922 is a code page used under IBM AIX and DOS to write the Estonian language. It is an extension and modification of ISO/IEC 8859-1, where the letters Ð/ð and Þ/þ used for Icelandic are replaced by the letters Š/š and Ž/ž respectively. This matches the encoding of these letters in Windows-1257 and ISO/IEC 8859-13.
