I don't necessarily know if this is a bug or not but in chat, forums and auctions. when I put a comma in a forum title, in chat, or in auction titles it does this:

ex. WasnÂ't.

It's weird though because I can see that some other people have the problem but some people don't.

hope y'all can fix it :)

It has to do with your keyboard I think.

It isn't a bug. It is from using smart punctuation on apple devices. You can turn it off and you won't have it anymore.
