各ブラウザが解釈可能なcharsetのリスト

各ブラウザがcharsetとして解釈可能な文字列の調査

A.テストの方法

以下にあるcharsetとして扱われそうな文字列をブラウザが認識できるか確認した。

IANAのcharacter-sets.xml
ICUのリスト
すいかサーバーさんで掲載されているcharsetのリスト
Mozillaのcharsetalias.properties.html
レジストリ (HKEY_CLASSES_ROOT\MIME\Database\Charset)
mlang.dll
Operaのインストールフォルダにあるopera.dll
apple.comにあるmac-encodings.txt

テストの具体的な方法はブログに書いた。 Masato Kinugawa Security Blog: 各ブラウザがサポートするcharsetのリスト

ブログに書いた方法とはやり方が少し異なるが、ここでテストできる→ http://l0.cm/encodings/check/

B.最後にテストしたブラウザ

Chrome 59/Safari 10.1(OS X)/Firefox 52.0.2/Opera 12.02/IE11(win8.1)/Edge(2017/4、Creators Update直後のWin10)/Android標準ブラウザ(2.3.6)/Safari(iOS 7.0.4)

C.テストの結果

Chrome Safari(OS X) Firefox Opera IE Edge Android safari(iOS)

メモ

各ブラウザが解釈可能なcharsetの比較表はこちら
古いブラウザのテスト結果はこちら(Safari 5.1.7 winなど)
Safari(OS X)、指定するとページが表示されなくなるcharset名がある。→"x-mac-vt100","iso-2022-jp-3","johab","jis_x0208-1983","jis_c6226-1978","jis_x0212-1990"
winとiOSのSafariのサポートするエンコーディングはほとんど同じ。違うのは、iOSが一部のエイリアス(ms949/unicode-1-1-utf-8/unicode-2-0-utf-8/windows-949-2000/x-KSC5601/x-roman8)をサポートしている点だけ。
Operaは「hz-gb-2312」をブラウザメニューから選択できるものの、実際にはhz-gb-2312に切り替わらない。
OperaはUTF-16LE/BEを解釈できるが、取得されるエンコーディング名にはLE/BEの表記上の区別がない。
BOMなしで「UTF-16」とだけ指定したとき、Opera以外はUTF-16LEとみなす。Operaは内容で自動選択しているようだ。どちらが選択されたときもdocument.characterSetの値は変わらず「UTF-16」のまま。BE/LEの判断材料がなければ、OperaはLEと判断しているようなかんじ。

OperaがBEと判断する例(BEで表示できれば「Opera」という文字が出る)
OperaがLEと判断する例(LEで表示できれば「UTF-16LE」という文字が出る)
~~FirefoxがBE/LEのヒントがない状態でBEを判断する例(BEで表示できれば「ＢＥ」という文字が出る)~~

→Firefox 20から「UTF-16」は「UTF-16LE」のエイリアスになったため、もはやBEとして認識されることはない。

OperaがBE/LEのヒントがない状態でLEを判断する例(LEで表示できれば「ＬＥ」という文字が出る)

Firefoxは、19でx-mac-romanをmacintoshに改名した。 https://bugzilla.mozilla.org/show_bug.cgi?id=802069
IEのx-cp21027、「8」「9」「=」など、必要な文字が欠けている。ここに記述あり→ http://blogs.msdn.com/b/shawnste/archive/2005/09/12/464278.aspx
XPのIE(IE6で検証)はContent-TypeのcharsetにunicodeFFFEを指定で、document.charsetが「unicodeFFFE」、VistaのIE(IE9で検証)は「unicodeFEFF」と、異なる値になる。

ところがXP/Vistaどちらも「unicodeFEFF」をContent-Typeのcharsetに直接指定しても認識してくれない。IE10win8/IE11win8.1は認識できるのを確認。

IEは、ホワイトスペースを含む「ISO-8859-8 Visual」をdocument.charsetからエラーなく代入できる。(IEのdocument.charsetへの代入では区切り文字は考慮されないようなので、間のホワイトスペースはcharset文字列の一部と扱われている。認識できない文字列なら、"引数が無効です。" というエラーになるはずだが、代入が成功する。よって、ホワイトスペースのあとの文字も含めてcharset名として認識していると考えられる。)
IEは、ブラウザメニューから「自動選択」や「日本語(自動選択)」を選択するとdocument.charsetが「_autodetect」になる(完全に読み込んだあとなど、エンコーディングが決定した段階でこの値は自動選択で選択された値に上書きされると思われる)。
IEは、Content-Typeヘッダのcharsetで指定すると、<meta charset=***>の値にかかわらず自動選択をしようとする文字列がある。「_autodetect」「_autodetect_all」など。

XP上のIEの場合についてはもう少し多い。cp930/cp933/cp935/cp937/cp939/x-ebcdic-japaneseanduscanadaなどもこれと同じ動きをする(Vista/7ではこれらの文字列はエンコーディングやエイリアスとして認識されない)。また、XPのIEではVista/7のIEでサポートされている一部のエンコーディングをサポートしておらず、それらを指定しても<meta charset=***>の値を無視する自動選択が起きる。
以下がVista/7ではサポートされているがXPでサポートされていない、特殊な自動選択が起きるエンコーディングの一覧。(※これらのエイリアスを指定した場合も同じ挙動になる。)

EdgeはUTF-7などのレガシーなエンコーディングのサポートを徐々に削除している。Anniversary Update後、XMLのみサポートを残していたときがあった。このサポートもCreators Update(2017/4)で削除された。

その他

もしリストにないエンコーディング(またはエンコーディングのエイリアス)・新しいバージョンのブラウザではもはや認識しないエンコーディング(またはエンコーディングのエイリアス)を発見したら、テストしたブラウザのバージョンなどとともにぜひTwitterなどで教えてください。

報告して頂ける場合、注意としては、

エンコーディング名の大文字小文字はどのブラウザも区別しない(はずな)ので、大文字小文字だけの違いは新しいエンコーディングとみなしません。 (例：Shift_JISとShiFt_jIsは同じと考えます)
エンコーディング名の区切りになる文字が一部あります。その区切り文字の後ろにはどんな文字列がきても、区切り文字より前の文字列がエンコーディング名とみなされる場合がありますが、それは新しいエイリアスとはみなしません。(例：「UTF-8,xxx」はUTF-8として識別されますが、これは「,(0x2C)」が区切り文字で、「,」より前の文字列をみてエンコーディング名を判断しているからです)

以下が各ブラウザのContent-Typeヘッダのcharset中で区切り文字と解釈されるバイト値です。

Chrome

0x09 0x20 0x28 0x2C 0x3B

Safari(OS X/iOS)

0x2C 0x3B

Firefox

0x09 0x20 0x28 0x2C 0x3B

Opera

0x09 0x20 0x2C 0x3B

0x09 0x0B 0x0C 0x20 0x3B

Android

0x09 0x20 0x28 0x2C 0x3B

※Androidは「,」について例外あり。「ISO_2022,locale=ja,version=0」(=ISO-2022-JP)のような表記もある。
