Legacy encoding
Appearance
In computing, a legacy encoding is a character encoding that continues to be used despite being obsoleted by another encoding. An encoding considered legacy in one context may remain the preferred encoding in another. Today the term is most commonly used in the context of Unicodification, where it refers to encodings that do not cover all Unicode code points. Even encodings which postdate the first Unicode standard, such as ISO-8859-15, may be considered legacy encodings in this usage.
