*
* @return Two-element array, where the first element (of type
* java.lang.String) contains the name of the (auto)detected encoding, and
* the second element (of type java.lang.Boolean) specifies whether the
* encoding was specified using the 'encoding' attribute of an XML prolog
* (TRUE) or autodetected (FALSE).
