Windows code page 1253 ("Greek - ANSI"), [1] commonly known by its IANA-registered name Windows-1253 [2] or abbreviated as cp1253, [3] [4] is a Microsoft Windows code page used to write modern Greek. It is not capable of supporting the older polytonic Greek.

Contents

It is not fully compatible with ISO 8859-7 because a few characters, including the letter Ά, are located at different byte values:

IBM uses code page 1253 (CCSID 1253 and euro sign extended CCSID 5349) for Windows-1253. [5] [6] [7]

Unicode is preferred for Greek in modern applications, especially as UTF-8 encoding on the Internet. Unicode provides many more glyphs for complete coverage, see Greek alphabet in Unicode and Ancient Greek Musical Notation for tables.

Footnotes

  1. ↑ This is in addition to the existing μ at 0xEC, which remains in place. Unicode calls the one at 0xB5 "micro sign" (U+00B5) and the one at 0xEC "Greek small letter Mu" (U+03BC), although the former is mapped to the latter by NFKC (although not NFC) Unicode normalization.

ISO/IEC 8859-3:1999, Information technology — 8-bit single-byte coded graphic character sets — Part 3: Latin alphabet No. 3, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1988. It is informally referred to as Latin-3 or South European. It was designed to cover Turkish, Maltese and Esperanto, though the introduction of ISO/IEC 8859-9 superseded it for Turkish. The encoding was popular for users of Esperanto, but fell out of use as application support for Unicode became more common.

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 8859-4:1998, Information technology — 8-bit single-byte coded graphic character sets — Part 4: Latin alphabet No. 4, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1988. It is informally referred to as Latin-4 or North European. It was designed to cover Estonian, Latvian, Lithuanian, Greenlandic, and Sámi. It has been largely superseded by ISO/IEC 8859-10 and Unicode. Microsoft has assigned code page 28594 a.k.a. Windows-28594 to ISO-8859-4 in Windows. IBM has assigned code page 914 to ISO 8859-4.

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.

ISO/IEC 8859-7:2003, Information technology — 8-bit single-byte coded graphic character sets — Part 7: Latin/Greek 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/Greek. It was designed to cover the modern Greek language. The original 1987 version of the standard had the same character assignments as the Greek national standard ELOT 928, published in 1986. The table in this article shows the updated 2003 version which adds three characters. Microsoft has assigned code page 28597 a.k.a. Windows-28597 to ISO-8859-7 in Windows. IBM has assigned code page 813 to ISO 8859-7. (IBM CCSID 813 is the original encoding. CCSID 4909 adds the euro sign. CCSID 9005 further adds the drachma sign and ypogegrammeni.)

ISO/IEC 8859-9:1999, Information technology — 8-bit single-byte coded graphic character sets — Part 9: Latin alphabet No. 5, is part of the ISO/IEC 8859 series of ASCII-based standard character encodings, first edition published in 1989. It is designated ECMA-128 by Ecma International and TS 5881 as a Turkish standard. It is informally referred to as Latin-5 or Turkish. It was designed to cover the Turkish language, designed as being of more use than the ISO/IEC 8859-3 encoding. It is identical to ISO/IEC 8859-1 except for the replacement of six Icelandic characters with characters unique to the Turkish alphabet. And the uppercase of i is İ; the lowercase of I is ı.

Windows-1250 is a code page used under Microsoft Windows to represent texts in Central European and Eastern European languages that use the Latin script. It is primarily used by Czech. It is also used for Polish, Slovak, Hungarian, Slovene, Serbo-Croatian, Romanian and Albanian. It may also be used with the German language, though it's missing uppercase ẞ. German-language texts encoded with Windows-1250 and Windows-1252 are identical.

Windows-1254 is a code page used under Microsoft Windows, to write Turkish that it was designed for. Characters with codepoints A0 through FF are compatible with ISO 8859-9, but the CR range, which is reserved for C1 control codes in ISO 8859, is instead used for additional characters. It matches Windows-1252 except for the replacement of six Icelandic characters with characters unique to the Turkish alphabet.

Windows-1255 is a code page used under Microsoft Windows to write Hebrew. It is an almost compatible superset of ISO-8859-8 – most of the symbols are in the same positions, but Windows-1255 adds vowel-points and other signs in lower positions.

Code page 950 is the code page used on Microsoft Windows for Traditional Chinese. It is Microsoft's implementation of the de facto standard Big5 character encoding. The code page is not registered with IANA, and hence, it is not a standard to communicate information over the internet, although it is usually labelled simply as big5, including by Microsoft library functions.

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. The original code page matched ISO/IEC 8859-13 directly.

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.
