Problem when user name is not alpha characters

[Venutius]

I think there should be a check put in place to stop users from registering with none alpha characters, or at least this is what my annecdotal evidence suggests.

I had a member register with a user name of colon semicolon, for some reason they thought is was a joke so they put in a smiley face.

That user did not show up in my user list all member view, I was however able to see them in another view and I asked them to change their name to something sensible, but I still had issues finding them in the user list, then later the account broke completely with the user not being able to log in with the correct password. I ended up having to delete that member profile and start from scratch.

So I'm concluding that there is a problem with those characters in some way, or maybe the username was just too short.

Are you using a plugin on your site which alters the registration process at all?

WordPress doesn't allow you to register a username that consists of only non-alphanumeric characters.
