> i can imagine issues even in European countries not used to middle names Are there any? Pretty much everyone I know in Europe has at least two given name and in some cases also two family names (Spain for instance). Here in Norway it is also common to have a first given name that is actually composed of two separate words without a hyphen, it looks like a name plus a middle name but is in fact what Norwegians call a double name and the person is addressed by both never by just one of them, see https://no.wikipedia.org/wiki/Liste_over_norske_dobbeltnavn https://no.wikipedia.org/wiki/Liste_over_norske_dobbeltnavn. And of course Icelanders don't use family names but instead use patronymics; for instance Björk Guðmundsdóttir where Björk's father's name is Guðmundur Gunnarsson and her mother's is Hildur Rúna Hauksdóttir. They might or might not have middle names. If you design a user interface that asks for a name please just let the user write the name as they wish with no restrictions on length and please don't try to force a surname into one box and a given name into another and don't forbid hyphens and spaces, etc.
