CSV export: export in unrecognized characters

Hi

I have activated the CSV export plugin. Unfortunately, when i open the csv file with Excel (Mac version), unrecognized characters appear, and when I use the Excel Windows version all fields are included in one cell again with unknown characters (you can see in the example below). I need to note that I am using either English or Greek language
