`Duplex` is used to send data to the connected peer, while the `Readable` side
is used to receive data sent by the connected peer.

The default text character encoding for all `Http2Stream`s is UTF-8. As a best
practice, it is recommended that when using an `Http2Stream` to send text,
the `'content-type'` header should be set and should identify the character
encoding used.

```js
stream.respond({
'content-type': 'text/html; charset=utf-8',
':status': 200
});
