TextDecoder.prototype.encoding

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The TextDecoder.prototype.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:

The recommended encoding for the Web: 'utf-8'.
The legacy single-byte encodings: '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'.
The legacy multi-byte Chinese (simplified) encodings: 'gbk', 'gb18030', and 'hz-gb-2312'.
The legacy multi-byte Chinese (traditional) encoding: 'big5'.
The legacy multi-byte Japanese encodings: 'euc-jp', 'iso-2022-jp', and 'shift-jis'.
The legacy multi-byte Korean encodings: 'euc-kr', and 'iso-2022-kr'.
The legacy miscellaneous encodings: 'utf-16be', 'utf-16le', and 'x-user-defined'.
A special encoding, '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.
