Sure, if you handle it gracefully and give them ample space to squeeze their names onto one field and your system not making fuss about it. People that tend to have fiften names also tend to come from areas that may use accented characters, have suffixes and thus spaces in their names and have other weird combinations: Cristina Fernández de Kirchner, Manuela Maria Lopez Sanchez de Chacon, Juan Carlos Vargas Blanco (given name is Juan Carlos, not Juan), Carla Rodriguez y Calderón (both Rodriguez and Calderón are last names) In my anecdotal experience from having lots of friends with non-ascii letters in their names there are surprisingly many websites and software that will fail to take into account some or all of those things. And then there are cultures where surname is not necessarily a thing. If you're adamant that users "can leave out" or butcher (because you don't accept Ü or Ł) their names because it's convenient to you then you're creating hard to predict problems for the user. Quite common is to accept all characters but then silently converting them for "convenience" before storing and then use those names next time instead of what the user entered, so that poor Łukasz would have to know to use Lukasz next time without nobody telling him.
