Ah, it's so interesting to contrast different approaches. For example, in Latvia, the legal treatment is that if you have two first names (two is the legal limit) then they are space delimited and if you have two surnames (it's becoming popular to join the surnames after marriage instead of changing the surname of one spouse) then they are hyphenated. So if you see "Alpha Beta Gamma" then that means Alpha and Beta as given names and Gamma as the surname; and "Alpha Beta-Gamma" means that Alpha is the given name and Beta-Gamma is the surname, so the name in any official documents can be unambiguously parsed.
