Hi Paul,
I had the same error when I was wanting to stop users from having a question mark in their usernames and it seemed to accept the new characters but then as you say once I did a test on a new user creation I got an error.
When I came back to the admin the initial two characters in the field appeared and the few I had added weren't even their then I submitted the page without changing anything and everything started working again.
