This problem cannot be reproduced by
- using onPrem IQ 16.1 since encoding parameter is not supported.
- using dbisql where same data file can be loaded with encoding option set to ‘ISO 8859 1’, and using option public.allow_read_client_file
  but when same file copied into HDLFS and try loading from DBX will crash Hana Datalake instance
