iSeries Bad Characters cannot translate with IBMDASQL in SSIS

I am using the IBMDASQL driver in SSIS to transfer from iSeries to SQL Server 2012. But the application programmers have some bad habits that mean character fields sometimes contain X'00' and X'FF' usually at the end of the meaningful data. I was hoping I could somehow use a translate table, but the nearest I get is the "Force Translate". I set this to zero (use the iSeries specific code page (is it code page?)) but that did not fix the problem.

Any ideas would be most welcome.

Thanks in advance,
Frank
