When I lived in Germany and on trips around Europe, I saw locals with UNC hats and shirts a lot. I have even seen our fan gear down under is Australia. In the eccentric 1994 comedy movie The Adventures of Priscilla, Queen of the Desert, there was a guy wearing an old UNC hat in an outback bar scene.
One Italian restaurant owner in Rome went nuts when he saw my UNC polo, he loved Jordan and UNC. He referred to me as "Mr. North-a-Carolina" when I returned.
Funny thing when I was in LA for a work trip last year I went up to the strip to get a Hollywood Harley-Davidson shirt. I was walking out of the parking garage and ran into another UNC alum when he noticed my UNC shirt, small world.
