[36] [DFN[[[Encoding]]]] は、 [[Web]] における[[文字符号化]]の扱いについて規定した仕様です。

* 仕様書

* 歴史

[99] 
元々 [[Web]] における[[文字コード]]処理の原則は[[参照処理モデル]]として緩やかに確立されていったのですが、
その詳細が明確に[[標準化]]されているとは言い難い状態でした。

** Web Encodings

[37] 当初 [[WHATWG Wiki]] の「Web Encodings」ページに [[annevk]] が [[Webブラウザー]]が実装する
[[charset]] の名前の情報を集めていました。

またこの頃までに、公式な仕様と現実の [[Webブラウザー]]で[[文字符号化]]の実装が異なっており、
例えば [[ISO-8859-1]] は現実には [[Windows-1252]] であることなどが認識され、
[[HTML Living Standard]] の規定に組み込まれていきました。

** Encoding Standard

[38] 2011年12月、 [[annevk]] は[[文字符号化]]の名前に加えて、符号化と復号の調査と文書化も始めました。

;; [39] 仕様書は [[W3C]] の [[Mercurial]] リポジトリーで管理されていましたが、
この時点では [[W3C]] の文書ではありませんでした。

[40] 2012年の春には [[TextEncoder]]/[[TextDecoder]] が提案されていますが、
その参照実装において [[Encoding]] 仕様に基づく符号化と復号が実装されています。

[41] 2012年4月末には仕様書は完成に至ります。ただし [[Big5]] については実装間の互換性に乏しく、
実情も十分わかっていないということで、未確定の部分を残しています。

[34] 2012年4月26日には [[WHATCG]] の仕様となり、 [[CC0]] から [[W3C]] [[CLA]]
に[[ライセンス]]が変更されました。また「Living Standard」から「Living Specification」
に変わっています。

[42] [[annevk]] は今後の展望として、[[文字符号化]]の [[sniffing]] の規定も含めたいと述べています。

[43] [[Microsoft]] は自社の実装を変更するつもりはないと述べています。
