I was curious about the resolution of that and looked it up. Turns out that the child's legal name is first name "X", middle name "AE A-XII", because "Æ" isn't a letter in modern English, and "12" isn't letters at all. So he'll still encounter several of the problems mentioned here (single letter name, hyphens, spaces), but at least not ones with computers systems requiring names be made of letters.

That hyphen though

Positive reading of the situation: if they get famous enough, as one is likely to with such a father and inheritance, maybe the next generation of programmers is more aware of what their systems should be capable of handling

Alternatively: poor kid, that name is going to be an annoyance without end

>On the birth certificate, it states that the baby’s first name is “X”, it’s middle name is “AE A-XII” and its last name is “Musk”.
