Character encoding.

Required Methods

Returns the canonical name of given encoding. This name is guaranteed to be unique across built-in encodings, but it is not normative and would be at most arbitrary.

Creates a new encoder.

Creates a new decoder.

Provided Methods

Returns a name of given encoding defined in the WHATWG Encoding standard, if any. This name often differs from name due to the compatibility reason.

An easy-to-use interface to RawEncoder. On the encoder error trap is called, which may return a replacement sequence to continue processing, or a failure to return the error.

Encode into a ByteWriter.

An easy-to-use interface to RawDecoder. On the decoder error trap is called, which may return a replacement string to continue processing, or a failure to return the error.

Decode into a StringWriter.

This does not handle partial characters at the beginning or end of input! Use RawDecoder for incremental decoding.
