I am unable to load a csv into a Snowflake Table via Matillion. The job throws an error as Invalid UTF8 detected in String. I have also tried to change the encoding type as ISO88591 (after i googled the error) but still unable to make the job run successfully. Any leads on what could be the issue? ---

[@Akshay](https://matillioncommunity.discourse.group/u/Akshay)​ - Not sure which operating system the files are on, but if they are on Linux/Unix you may want to try a grep to see find the invalid UTF8 characters and see if they are junk or actual data.

Had the same issue just now and switching to the ISO 88591 encoding type worked.
