*Beton* means “concrete” in French and various Slavic languages, so it shouldn’t be used whatsoever. Still, I checked StreetView on most locations to see if *fence_type=concrete* applied or if better tagging was possible. The location in Togo didn’t have StreetView, but since it’s a university, I could find photos of the premises. A few locations in Africa and Dominican Republic had neither, so I trusted the original editor regarding the actual material of the fence.
