public String getEncoding()
If the encoding has an historical name then that name is returned; otherwise the encoding's canonical name is returned.
If this instance was created with the OutputStreamWriter(OutputStream, String)
constructor then the returned
name, being unique for the encoding, may differ from the name passed to
the constructor. This method may return null if the stream has
been closed.
