What to do about write(CharBuffer)?

[Martin Buchholz]

In the general case, an encoder needs to know whether there is
more input, not just for error detection, but also for
producing the correct output.
If some encoder produced different output for
x
and
x + UMLAUT
then if the last char is 'x' we need some more input
or we need to know that there will be no more.

Again in the general case the encoder will need to
maintain state between encodes of CharBuffers, and the behavior
may be different on the final one.
