Username with "?" breaks quote formatting.

[TonyRPH]

Then I try without the question mark.

Who me said:

And this should have worked.

I quoted user "Who me ?" and it breaks the quote system.

Where this doesn't.

[quote=Who me ?]

This should be quoted.

[Kinky]

Yup

And not only a ?

This is on the bugs list already, but is quite fiddly to fix.

We've also changed the sign up system so people can no longer pick usernames with characters in which break the quoting etc, but we are not going to force users who already have them to change.
