It buffers the "EOF byte" when in streaming mode, eg. when the last byte of
the stream is a UTF-8 continuation byte, so any encode errors are triggered.

* TextEncoder.encode()'s input argument is no longer nullable. Again,

Likewise for encoding, to flush errors for trailing high surrogates.

I also raised the issue of whether TextEncoder should really support

The whole point of this API is to support legacy file formats that use
other encodings.  (It's probably questionable to not support other
encodings, too, eg. filenames in ZIP file headers, but starting out with
Unicode is fine.)
