I have a company in Finland whose legal name contains the + character.
It’s always a modest thrill to interact with new computer systems and see if and how they break. Some web forms just can’t be submitted because my company’s legal name has been autofilled from the registry and is not an editable field, but then they have a validator that won’t allow the string that their own system inserted into the form.
The best part is when in one year you supply a fully correct government issued ID to the e-gov site. And years later you can't use that ID because it's auto filled but nowadays it's a two fields instead of one.
