The problem is out-of-support and I've used it for years. And it works perfectly... except.. as you deduced it puts that stuff in when it is exporting to a CSV file. I don't know how to upload the broken data. When I open it in my text editor, it has no problem with it but when I go and save the file the UTF-8 is all still there. I loaded it into Excel, it loaded fine and showed no anomalies, but when I saved it from excel all the UTF-8 stuff was still there. There's no pattern I can tell for why there are the byte-order-markers strewn through the file.

What should I do either to upload something to here with example probelmatic stuff and/or be able just to brute-force fix it?
