I think Sweden is one of those countries, eloethan. DD2 lived there for a while and told me.
While I prefer classic names myself, I also think it too authoritarian for governments to prevent people from giving their kids weird names. I'm thinking of the film "Dances With Wolves" (one of my favourites), and the Native North American custom it highlights of a person 'earning' their name by other people's observations of their character and behaviour. I like that tradition and think that some of the name weirdness we now encounter is a similarly cultural thing.
And after all, all names were made up originally. Look at a book on name meanings. Many of what we now regard as classic names have equally weird original meanings. I have nephews and nieces called Manly, Bright, Ewe, Beloved, Who-is-like-the-Lord, Noble Kind, God is Gracious, Watcher.
