special characters from git to eclipse

So I am cloning some java files from git to eclipse. There are special characters like Ü è. letters you would see in the Spanish language that java normally does not like. When I open up the project in java it turns them into the square with the ? in the middle of it and java complains about it saying there is a special character problem. It wouldn’t be that big of a problem but I’m doing it for work and there are A LOT of code and go through and a lot of special characters. Anything I can do about this to either make java like it or not change the characters when I go from git to eclipse?
