Elon Musk tried to name his kid X Æ A-12.
Musk's partner at the time, Grimes, and Musk himself, explained the meaning behind the name, but it was reported that this name did not comply with California naming laws because it contained characters that are not part of the English alphabet. The name was later changed to X Æ A-Xii. The pronunciation of "X Æ A-12" is also a point of interest, as seen by the reference material.
