You're right. It isn't the symbol for "J", but I think it's an animation error. I think it could be the author's letter for "p". In a symbol substitution cipher, you can't have one image/symbol represent more than one letter. And, there is no reason why only one letter in the whole message would be in Bill's symbol (unless he was just messing, but even so that was before he was summoned)
