As soon as an octet is encountered which renders the octet sequence invalid, a quad with ``valid? == False`` is returned. ``currentIndex`` returns the index within the currently consumed chunk, and ``totalIndex`` the index within the total consumed sequence that was the point of bail out. When ``valid? == True``, currentIndex will be ``len(ba)`` and ``totalIndex`` the total amount of consumed bytes. rrr FrT)lenrr UTF8_REJECTrr )rbalistates rvalidatezUtf8Validator.validatews"BAAKEa%%+C5A:,>ATUWXYUZA[,[\K''"'DKKK1$KK %DK77Qa%% DK KK1 KK+-q$+= =rN) __name__ __module__ __qualname____doc__ __slots__rr#rr,rrrrHsa          &    > > > > >rrN) __all__UTF8VALIDATOR_DFAr r'wsaccel.utf8validatorr ImportErrorbytesrobjectr2rrr9s> "  \>33333333Y>Y>Y> % 122M>M>M>M>M>M>M>M>M>M>M>Y>s 44
