Cause

Your .csv file was not saved in the Unicode (UTF-8) format for Windows. When you save please be sure to specify the format it is encoded in. 

Solution

If you are using a Mac computer, you will need to specify as CSV for Windows when you save. 

Otherwise, open the file in Windows Notepad (or equivalent that gives you the option to save in UTF-8 format) then Click Save As, choose the UTF-8 Format and then save.
