@ananas that is just wrong beyond any forgiveness

5. Encode values in anything but UTF-8

@mawhrin @rail_ fun fact, my uncle had a very common (out at least used to be common when immigration happened) German last name: Dick.

With that spelling.

There were several people in my area that had trouble with work email and spam filters

@sashin yes and yes

First because a lot of places don't use "last names" at all, or use them differently and a different order than you do. It should be a single field that does not require any nor put a limitation on number of space separations

Second, because your "swears" and other bad words can be valid names that people have, or can mean something completely different in other cultures

I wonder how many times Arnold Schwarzenegger had issues because of that ;p

@we_are_spc people without a last name exist and it's not very uncommon

people with more than one last name exist and in many places it's very common

people with multiple first name exist and it's extremely common

what is a valid name depends on culture and individual person

there is no such a thing as an invalid name and it shouldn't be your job to try to validate them

good practice is one field for "Full name" and a nice touch is a separate, optional field for "How do you want to be referred to"
