> For the purposes of backward compatibility, client attempts to send the database converted
to Ebcdic in the server attributes.  If it cannot, it will continue and send it in subsequent
code points where it can send in UTF-8.
> If a trace file is specified, e.g. with ClientDataSource.setTraceFile()   the trace file
shows the exception and trace.  It might be confusing to have it in the trace file when it
results in no real exception.  Maybe just a line that it could not be sent on EXCSAT or maybe
nothing at all would be fine.
