Ingres import assistant error with utf 8 vector wise

Hi there,
Notes about the BOM in UTF8 Files and Importing Data Into VectorWise on Windows gives me this error. I have no idea about this error or how can I solve this error. Can anyone help me please to fix this error ? What is wrong with my PC ?
Thank you !
