   * the type is Buffer, then the encoding must be missing, or set to
   * 'buffer' or null. If the type is anything else, then objectMode
   * must be set in the constructor options.  So there is effectively
   * no allowed way that a TS program can set the encoding after
   * construction, as doing so will destroy any hope of type safety.
   * TypeScript does not provide many options for changing the type of
   * an object at run-time, which is what changing the encoding does.
