Topic: Bug with using a special Alt-code character
I made a topic in Test Forum just now so that you can see what I mean.
If you enter Alt+0173 into a topic title, post message, or presumably anywhere in PunBB, you can bypass the validation of 'required fields'.
First Google result to help explain: http://encyclopediadramatica.com/Alt-0173
I'm not sure if there's anyway to protect against that, but I thought I'd post it anyhow.
