UTF-8 Encoding Problem (Greek)

`Hello Everyone, i’ve been facing a problem as of recent.
I’m trying to implement ARmember into a website with alumni members and while it works fine, and it covers my needs, there is a pretty big issue.

The Goal :
Import about 9k Members with the respective information.

The Problem :

While i have managed to import everything in English, I can’t get the Greek encoded characters to import without having them show up as “Σ” instead of Greek letters.

Things I’ve tried so far and nothing worked :
– Removing the UTF-8 Encoding from the class.arm_members.php file ( Path : plugins\armember-membership\core\classes )
– Saving the CSV as a TXT on Notepad ++ with utf-8 and converting it to utf-8, then renaming the extension back to CSV.
– Every kind of different save method I could find on Excel for UTF-8.
– Saving it as UTF-8 and/or UTF-8 BOM
– Trying to import an XML instead of the CSV with the same data.

Nothing seems to work, and the characters still appear as “Σ”.

Any help or suggestion would be appreciated.
