Fix the wildcard-term ban for special characters
So I'm not sure in which cases the wildcard-term ban doesn't work correctly, but on a channel I'm moderating we would like to block the "^^" smiley, unfortunately blocking "*^^", "^^*" or "*^^*" doesn't solve the problem. I suspect that there is a general problem with special characters in wildcard terms.
AFAIK, there is no wildcard. I could be wrong, though, but i've made a whole new bot to address this.
