Additional information on this point: "Sweat of the brow" [1] is a doctrine which grants copyright on a work due to the time and effort the author put into making it. The US Supreme Court rejected this doctrine, meaning that only the creative aspects of a work are relevant to copyright. For that reason, in the US, a phone book is not copyrightable unless the arrangement of its contents is creative [2]. The EU narrowly rejects "sweat of the brow" copyright for recreations of public domain visual art [1]. I have no idea whether the same applies to font faces, public domain non-visual art, or phone books, but I'm assuming that it doesn't.
