docs: Print a string.  If the argument is <code>null</code> then the string
  <code>"null"</code> is printed.  Otherwise, the string's characters are
  converted into bytes according to the platform's default character
  encoding, and these bytes are written in exactly the manner of the
  <code>{@link #write(int)}</code> method.
