{{Short description|Sets of characters used in the 1980s & 90s}}
'''Windows code pages''' are sets of characters or [[code pages]] (known as [[character encoding]]s in other operating systems) used in [[Microsoft Windows]] from the 1980s and 1990s. Windows code pages were gradually superseded when [[Unicode in Microsoft Windows|Unicode was implemented in Windows]],{{cn|date=October 2020}} although they are still supported both within Windows and other platforms, and still apply when [[Alt code]] shortcuts are used.
 
Current Windows versions support [[Unicode]], new Windows applications should use Unicode (UTF-8) and not 8-bit character encodings.<ref>{{cite web |url=https://learn.microsoft.com/en-us/windows/win32/intl/unicode-and-character-sets |title=Unicode and character sets |publisher=Microsoft |date=2023-06-13 |access-date=2024-05-27}}</ref>
There are two groups of system code pages in Windows systems: OEM and Windows-native ("ANSI") code pages.
 
There are two groups of system code pages in Windows systems: OEM and Windows-native ("ANSI") code pages.
(ANSI is the [[American National Standards Institute]].) Code pages in both of these groups are [[extended ASCII]] code pages. Additional code pages are supported by standard Windows conversion routines, but not used as either type of system code page.

Most [[Legacy system|legacy]] "ANSI" code pages have code page numbers in the pattern 125x. However, [[windows-874|874]] (Thai) and the East Asian multi-byte "ANSI" code pages ([[Windows-31J|932]], [[windows-936|936]], [[Unified Hangul Code|949]], [[Code page 950|950]]), all of which are also used as OEM code pages, are numbered to match IBM encodings, none of which are identical to the Windows encodings (although most are similar). While [[windows-1258|code page 1258]] is also used as an OEM code page, it is original to Microsoft rather than an extension to an existing encoding. IBM have assigned their own, different numbers for Microsoft's variants, these are given for reference in the lists below where applicable.
 
All of the 125x Windows code pages, as well as 874 and 936, are labelled by [[Internet Assigned Numbers Authority]] (IANA) as "Windows-''number''", although "Windows-936" is treated as a synonym for "[[GBK (character encoding)|GBK]]". Windows code page 932 is instead labelled as "Windows-31J".<ref>{{Cite web

ANSI Windows code pages, and especially the code page [[Windows-1252|1252]], were so called since they were purportedly based on drafts submitted or intended for ANSI. However, ANSI and [[International Organization for Standardization|ISO]] have not standardized any of these code pages. Instead they are either:<ref name="ms glossary"/>
Line 36 ⟶ 56:
The '''OEM code pages''' ([[original equipment manufacturer]]) are used by [[Win32 console]] applications, and by [[virtual DOS machine|virtual DOS]], and can be considered a holdover from [[DOS]] and the original [[IBM PC]] architecture. A separate suite of code pages was implemented not only due to compatibility, but also because the [[VGA-compatible text mode#Fonts|fonts of VGA (and descendant) hardware]] suggest encoding of [[box-drawing character|line-drawing characters]] to be compatible with [[code page 437]]. Most OEM code pages share many code points, particularly for non-letter characters, with the second (non-ASCII) half of CP437.
 
A typical OEM code page, in its second half, does not resemble any ANSI/Windows code page even roughly. Nevertheless, two single-byte, fixed-width code pages (874 for [[Thai language|Thai]] and 1258 for [[Vietnamese language|Vietnamese]]) and four multibyte [[CJK characters|CJK]] code pages ([[Code page 932 (Microsoft Windows)|932]], [[Code page 1386|936]], [[Windows-949|949]], [[Windows-950|950]]) are used as both OEM and ANSI code pages. Code page 1258 uses [[combining diacritic]]s, as Vietnamese requires more than 128 letter-diacritic combinations. This is in contrast to [[VISCII]], which replaces some of the [[C0 control codes|C0]] (i.e. ASCII) control codes.
 
== History ==
Initially,Early computer systems had limited storage and systemrestricted programmingthe languagesnumber didof not[[bit]]s makeavailable ato distinctionencode betweena [[character (computing)|character]]. Although earlier proprietary encodings had fewer, the [[ASCII|American Standard Code for Information Interchange]] (ASCII) settled on seven bits: this was sufficient to encode a 96 member subset of the characters used in the US. As eight-bit [[byte]]s came to predominate, Microsoft (and others) expanded the repertoire to 224, to handle a variety of other uses such a box-drawing symbols. The need to provide [[byteprecomposed character]]s for the Western European and South American markets required a different character set: Microsoft established the principle of code pages, one for each alphabet. For the [[List of writing systems#Segmental script|segmental scripts]] used in most of Africa, the Americas, southern and south-east Asia, the Middle East and Europe, a character needs just one byte, but two or more bytes are needed for the [[ideographic]] sets used in the rest of the world. ThisThe ledcode-page tomodel muchwas confusion subsequently. Microsoft software and systems priorunable to the [[Windows NT]] line are examples ofhandle this, because they use the OEM and ANSI code pages that do not make the distinctionchallenge.
 
Since the late 1990s, software and systems have adopted [[Unicode]] as their preferred storage format; this trend has been improved by the widespread adoption of [[XML]], which provides a more adequate mechanism for labelling thecharacter encoding used.<ref>{{cite web | url = httpformat://www.w3.org/TR/xml11/#charencoding |Unicode titleis =designed Extensibleto Markuphandle Languagemillions (XML)of 1characters.1 (Second Edition): Character encodings | publisher = [[W3C]] | date = 29 September 2006 | access-date = 5 October 2020 | archive-date = 19 April 2021 | archive-url = https://web.archive.org/web/20210419133700/https://www.w3.org/TR/xml11/#charencoding | url-status = live }}</ref>All Recentcurrent Microsoft products and [[application program interfaces]] use Unicode internally,{{cn|date=October 2020}} but manysome applications and APIs continue to use the default encoding{{clarify|date=October 2024}} of the computer's 'locale' when reading and writing text data to files or standard output.{{cn|date=October 2020}} Therefore, files may still be encountered that are legible and intelligible in one part of the world but unintelligible [[mojibake]] in another.
 
=== UTF-8, UTF-16 ===
Microsoft adopted a Unicode encoding (first the now-obsolete [[UCS-2]], which was then Unicode's only encoding), i.e. [[UTF-16]] for all its [[operating system]]s from Windows NT onwards, but additionally supports [[UTF-8]] (aka <code>CP_UTF8</code>) since [[Windows 10 version history#Version 1803 (April 2018 Update)|Windows 10 version 1803]].<ref>{{cite web
Microsoft decided to adopt the 16-bit (two-byte) [[UTF-16]] system for all its [[operating system]]s from Windows NT onwards. This method encodes uniquely all Unicode characters in the [[Basic Multilingual Plane]] and a 32-bit (four byte) code for others{{snd}} but the rest of the industry ([[Unix-like]] systems and the web) chose [[UTF-8]] (which uses one byte for the 7-bit [[ASCII]] character set, two or three bytes for other characters in the BMP, and four bytes for the remainder). Since [[Windows 10 version history#Version 1803 (April 2018 Update)|Windows 10 version 1803]], Windows machines can be configured to allow UTF-8 as the "ANSI" and OEM codepage.<ref>{{cite web|url=https://srad.jp/story/17/11/14/0640253/|title=Windows 10のInsider PreviewでシステムロケールをUTF-8にするオプションが追加される|trans-title=The option to make UTF-8 the system locale added in Windows 10 Insider Preview|author=hylom|website=スラド|language=ja|date=2017-11-14|access-date=2018-05-10|archive-date=2018-05-11|archive-url=https://web.archive.org/web/20180511012606/https://srad.jp/story/17/11/14/0640253/|url-status=live}}</ref>

UTF-16 uniquely encodes all Unicode characters in the [[Basic Multilingual Plane]] (BMP) using 16 bits but the remaining Unicode (e.g. [[emoji]]s) is encoded with a 32-bit (four byte) code{{snd}} while the rest of the industry ([[Unix-like]] systems and the web), and now Microsoft chose [[UTF-8]] (which uses one byte for the 7-bit [[ASCII]] character set, two or three bytes for other characters in the BMP, and four bytes for the remainder).

== Problems arising from the use of code pages ==
Line 261 ⟶ 404:
* The use of code pages limits the set of characters that may be used.
* Characters expressed in an unsupported code page may be converted to question marks (?) or other [[replacement character]]s, or to a simpler version (such as removing accents from a letter). In either case, the original character may be lost.
 
== See also ==
* [[AppLocale]]&nbsp;– a utility to run non-Unicode (code page-based) applications in a locale of the user's choice.
