Hi Ian, I do have NVARCHAR2 columns and the NLS_NCHAR_CHARACTERSET is AL16UTF16 in both schemas.
When trying to decode and encode according to your instruction I get: UnicodeEncodeError: 'latin-1' codec can't encode characters in position 4171134-4176189: ordinal not in range(256) When looking at that position in the file I discovered that we had some "chinese" chars there. And they shouldn't be there (-there seems to be a problem when the size of a oracle CLOB field is exceeded). So now I fount out what the problem is and I thank you for your help..
