Mike Beckerle commented on DAFFODIL-1898:
-----------------------------------------
I found this comment in the TDMLRunner in the definition of method
{code:java}
def decodeDataToString(decoder: BitsCharsetDecoder, bytes: Array[Byte]): String
....
// Decoders don't actually need much of the formatinfo. Byte size
// decoders don't ever refernce byte/bitOrder, they just read raw bytes
// from the underlying data stream. And non-byte size encoders do care,
// but only support bigEndian/LSBF. There should never be encoding
// errors, so the error policy doesn't really matter.
{code}
This is patently false at this point, there are not byte-sized encodings that
use both MSBF and LSBF bit order.
This seems likely to be the cause of the problem.
> TDML Runner not assembling mixtures of BE+MSBF and LE+LSBF test data properly.

> See test testMixedBigEndianMSBFWithLittleEndianLSBF
> Also the test test_ep3 had to work around the bug. See the tdml file for this
