Writes chars from a <code>CharSequence</code> to bytes on an
<code>OutputStream</code> using the specified character encoding.

@param output   the <code>OutputStream</code> to write to
@param encoding the encoding to use, null means platform default
@throws NullPointerException if output is null
@throws IOException          if an I/O error occurs
