What this means is "we don't know what the fuck the encoding is in the
incoming data, so just try random shit until something appears to
work".  I would prefer a more thought-out approach.

We should not need to check the flag.  The incoming data should be
encoded.  Then we should decode it.  Then we should not try to decode it
again.
