It is quite common for names to need administrative approval in Europe. Rarely is that an obstacle, it's just so that people don't name their kid "Fuck", "X Æ A-12" or something else that could cause them to have problems in life (that also can apply to foreign language names – the US is very liberal in this aspect, being made up of immigrants, but many European countries aren't).
