Is there a way to stop Rider from editing the documents encoding?

I'm a developer working in Sweden so I use åäö (swedish charachters alot). I never had a problem with this in Visual Studio but Rider doesnt seemt to get the encoding right so it change every instance of å, ä or ö to �. 
Is there any way to stop Rider from doing this? It gets to the point that I have to change a lot of files in git manually everytime I use Rider in some projects. 

Kinda desperate here…
