Encoding API Encodings
The constructors for the Encoding API interfaces TextDecoder and TextDecoderStream can be passed an optional label, representing the encoding to be used.
The default is UTF-8.
The following table lists all encoding names and labels that user agents must support, as defined in the Encoding Spec. These are generally applicable anywhere character encodings are used.
