This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
http://encoding.spec.whatwg.org/#interface-textdecoder [[ A TextDecoder object has an associated encoding, encoder, stream, BOM seen flag (initially unset), error mode (initially replacement), and streaming flag (initially unset). ]] It looks like there should be "A TextDecoder object has an associated encoding, decoder". "decoder" instead of "encoder". Because it uses 'decoder' of 'encoding' entity.
Thanks! https://github.com/whatwg/encoding/commit/1ca60ca6720e8a4ed28d9ee38047a063cfb21f3a
