Class diagram interface with classes not adding any new methods

I'm in the process of creating a hangman game for Android, but I'm unsure about some parts of the class diagram. I have an Alphabet Interface With Methods for resetting, check if a letter is guessed, and marking it as guessed if it is not previously guessed.

The app will support both the Norwegian and English alphabet which means the the implementation of Methods will differ some.

In the class diagram, is it fine to leave the classes implementing the Interface empty or should I never do it this way unless they add New functionality?

Generally speaking your class diagram should contain as much detail as is needed to get the full picture without including every little detail. Someone unfamiliar with your project should be able to take it and implement it without asking too many questions.

If you have classes who's only purpose is to be a union of interfaces, those should be included in the diagram if they should be instantiated, even if they are empty. But generally they would not be empty..they would at least have a few members to keep track of things.
