Abstract

RFC 2482, "Language Tagging in Unicode Plain Text" [RFC2482], describes a mechanism for using special Unicode language tag characters to identify languages when needed. It is an idea whose time never quite came. It has been superseded by whole-transaction language identification such as the MIME Content-language header [RFC3282] and more general markup mechanisms such as those provided by XML. The Unicode Consortium has deprecated the language tag character facility and strongly recommends against its use. RFC 2482 has been moved to Historic status to reduce the possibility that Internet implementers would consider that tagging system an appropriate mechanism for identifying languages.

    Deprecating Unicode Language Tag Characters: RFC 2482 is Historic

Abstract

   RFC 2482, "Language Tagging in Unicode Plain Text", describes a    mechanism for using special Unicode language tag characters to    identify languages when needed without more general markup such as    that provided by XML.  The Unicode Consortium has deprecated that    facility and strongly recommends against its use.  RFC 2482 has been    moved to Historic status to reduce the possibility that Internet    implementers would consider that system an appropriate mechanism for    identifying languages.
