That reminds me of my own pet peeve regarding anglocentric UI assumptions. Spanish naming customs are 'Given_name First_surname Second_surname' [0], such as for example Spanish director Pedro Almodóvar Caballero, whose name would be shortened for convenience by dropping the second surname — Pedro Almodóvar. The problem is too many US/Aus/UK developed UIs assume the whole world follows English naming customs, and thus would insist on showing his initials as 'PC' or shortening his full name as 'Pedro A. Caballero'. For reference, that feels as wrong as it would be to an American for a website (assuming Spanish customs) to initialise the director of E.T. and Jurassic Park as 'SA' or display his full name as 'Steven Allan'.

[0] Spanish given names may often be two-words-long (e.g. 'José Manuel') and a surname may less frequently be more than one word (e.g. 'de la Fuente'), but this isn't a necessary detail for my base rant above.

And the inverse is also somewhat common- forms which require both a maternal and paternal surname, and won’t let you continue with just a single surname.

That’s not even a totally UI concern. See https://www.kalzumeus.com/2010/06/17/falsehoods-programmers-...

In José Manuel, Manuel would be the middle name, just like in English. It's not a "two-words-long first name". Sometimes first and middle names are coupled like a whole, like it's usual for José Manuel. Also for José-something or Juan-something in general. Other times, the middle name is never used, like in Nicolás Antonio, being the Antonio part extra annoying, because the SS personnel, for some reason, insists in calling me that when it's my turn.

My wife's sister decided to name their two newborns with three names, on top of the usual two surnames.

I wish luck to those two little guys, as their names will be misrepresented pretty much in every system in the world.

Wait, what? We don't have middle names, we have "nombres compuestos". Sometimes you may drop part of the name, sometimes not, but you will never see a form with a field for the middle name like you see in English speaking countries.

So different ways of calling the same thing and different UIs. But it's just given names vs. family names and a set of rules. I like Bulgarian ones most.
