My middle name is "Fabæch". Or actually it's legally part of my first name, probably because the Danish Civil Registration Number was established in 1968 and was at the bleeding edge of what was possible with computers back then. So no field for middle names, so a secondary first name it is. In actual reality it has been passed down my family so that should logically make it a "family name", which would be a last name in usual western name order.
So far I haven't had any real problems, just annoyances. Often when buying something online the page wants me to write my full legal name "exactly as written on the card" - and then promptly refuses my full legal name. I have even had sites saying something along the line of "Validation Error: Invalid name". That's really not a good look...
With airlines they usually tell me to write my first and last name "exactly as written" in my passport, and then refuses to accept the 'æ'. At least airlines have a standardized substitution of 'æ' -> 'ae' and so far I haven't encountered any problems using that. It's also what it says in the machine readably part of the passport, so I guess that is really what they mean by "exactly as written in my passport".
