This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.
The TextDecoder.encoding read-only property returns a DOMString containing the name of the decoding algorithm used by the specific decoder.
It can be one of the following values:
'utf-8'.'ibm866', 'iso-8859-2', 'iso-8859-3', 'iso-8859-4', 'iso-8859-5', 'iso-8859-6', 'iso-8859-7', 'iso-8859-8'', 'iso-8859-8i', 'iso-8859-10', 'iso-8859-13', 'iso-8859-14', 'iso-8859-15', 'iso-8859-16', 'koi8-r', 'koi8-u', 'macintosh', 'windows-874', 'windows-1250', 'windows-1251', 'windows-1252', 'windows-1253', 'windows-1254', 'windows-1255', 'windows-1256', 'windows-1257', 'windows-1258', or 'x-mac-cyrillic'.'gbk', 'gb18030', and 'hz-gb-2312'.'big5'.'euc-jp', 'iso-2022-jp', and 'shift-jis'.'euc-kr', and 'iso-2022-kr'.'utf-16be', 'utf-16le', and 'x-user-defined'.'replacement', which only emits an error and an EOF code point. It is used to prevent attacks that mismatch encodings between the client and server. It can happen with ISO-2022-CN and ISO-2022-CN-ext.b = decoder.decoding;
