This makes me really curious about how people with legal mononyms (Ye, Cher, etc.) have their taxes filed or medical forms filled out.

On paper forms you usef to just draw a line theough the field to make clear that you didn't just forget. I've seen electronic forms that require you enter "N/A" for the same. Would be amusing if someone chamged their name to "N/A".

In some countries it's not legal. If it is legal then you complain, you muddle through, you accept compromises like an extra space in a few cases.
