DB2 source issue in SAP BODS

I am using DB2 source for extracting data in my project. (As source)

I get the below warning when

[IBM][CLI Driver][DB2/LINUXX8664] SQLSTATE 01517: A character that could not be converted was replaced with a substitute

  character.

so for the tables with high count , These warnings get piled up resulting in Internal internalisation error.

When i browsed about this warning online , it was mentioned as code page issue.

I checked the values in source DB2server - which was as given below.

Database territory                                      = en_US

Database code page                                      = 1208

Database code set                                       = UTF-8

Database country/region code                            = 1.

I changed my client machine Environment values to the same values as well(Snapshot attached)

I have changed it in my source datastore values as well. (Snapshot attached)

Can you guys help me on this issue, any suggestion/help will be deeply appreciated.

Thanks

Arun.
