Encoding API Encodings
{{DefaultAPISidebar("Encoding API")}}
The constructors for the Encoding API interfaces {{domxref("TextDecoder")}} and {{domxref("TextDecoderStream")}} can be passed an optional label argument, which identifies the encoding to be used.
The following table lists all encoding labels that user agents must support, along with the encoding that the label identifies. Note that most encodings have more than one label.
