Data upload thru OLE DB Provder from SQL 2005 to Teradata-Issue with special chars

We are using OLE DB Provider for uploading the data from SQL server 2005 to Teradata using AMJ files, etc. While uploading the data which has some junk chars but that was accepted by SQL server 2005 failed during MLoad Acquisition phase.

Can anyone help me regarding this?
