In computing, a '''legacy encoding''' is a [[character encoding]] that can't represent all of [[Unicode]], but is still used for compatibility or other reasons.<ref>[http://www.ibm.com/developerworks/library/unicode-db-process/ "Processing database information using Unicode, a case study"], [[IBM]] developmentWorks, [[1 September]] [[1999]] </ref>
Many legacy encodings predate Unicode, while others are slight modifications to older encodings to support important new characters such as the [[euro sign]] (€) or to satisfy countries that felt there were significant omissions for their language. The best known such encoding is probably [[ISO-8859-15]].
Legacy encodings are numerous, and include the following major groups:
* The [[ISO-8859]]-n group of single byte encodings
* The [[IBM]]/[[DOS]]/Windows OEM series of single byte [[code page]]s (437, 850, and others).
* The single-byte Windows [[Code page#Microsoft code pages|"ANSI" code page]]s (125x)
* The windows multibyte code pages used by windows as both ANSI and OEM code pages for [[CJK]] languages.
* Various other multibyte CJK encodings such as [[ISO-2022]] and [[EUC]].
