This class implements a character buffer that can be used as an Writer.
The buffer automatically grows when data is written to the stream. The data
can be retrieved using toCharArray() and toString().
Note: Invoking close() on this class has no effect, and methods
of this class can be called after the stream has closed
without generating an IOException.
