Keypair update returns unclear error with invalid name

[Scott Devoid]

Nova returns 400 error "Keypair data is invalid" if the key name contains anything outside of basic ASCII alphanumeric, "-" or "_".

-I don't see a reason for this. Our external key management system handles full unicode key names fine.-

Edit:
Updated bug status. I suggest defining a specific error "Keypair name contains invalid characters" (still 400) for more clarity.

I would suggest clarifying the error text. E.g. "Keypair name contains unallowed characters" or "Keypair public key is invalid". I spent a long time confirming that the public key was being passed in correctly when the keypair name was triggering an error.

I can confirm that the error text is now more descriptive:
ERROR: Keypair data is invalid: Keypair name contains unsafe characters
