**Root Cause:**The Csv data file contains foreign/special characters and have invalid encoding. Hence the error due to unsupported encoding type of the data

**Solution: **The foreign/special characters needs to be removed and it is required to be made sure that data is under UTF-8 encoding.  Since we use and support UTF-8 encoding
