Is this the right forum for SMS questions?

I have supplied some code to Germans which uses NWSMPutOneLName() followed by NWSMTSScanDataSetBegin() and it seems to be failing on files which have umlauts in the name.

The error from the scan is: ( 6.50.0 269) No data sets can be found or the resource is not available. (FFFDFFF2)

Is this a known issue? Would a more recent library fix it. The code was built under OES 9 SP1.

All comments welcome...
