If you cannot validate names, then you probably should not use a real name policy. It bad enough Facebook (and I guess Quora) causes people pain, don't add your own wounds.
Her legal name at this point clocks in at enough words and characters to not fit in most government databases. I've been tempted once or twice to create a similar but fake name to use as a test case for things that handle identity information.

I've had countless problems with this and delays in getting stuff transmitted or done because people won't believe it's me or won't understand why I have a second last name (which I or my family never asked for when moving here). If just one extra word causes problems, I can't imagine what other cultures have to deal with! No wonder European immigrants a hundred years ago Americanized their names when moving here :-)
I do have two wonderful? related problems now though: I come across the occasional racist jerk that I can learn to avoid because they can't help Questioning my last name not matching my ethnicity, and I come across people that don't realize that my name in my other language hasn't changed (and that that's just not a Thing that happens in that culture). Yay names.
