I am just wondering after seeing this question : PHP JSON Special Characters , which has a bounty worthy of 100 reputation, with a reason showing as "One or more of the answers is exemplary and worthy of an additional bounty." But as you will see there is only one answer (already accepted) which is posted by the bounty owner himself.
As far as know, the bounty owner cannot award himself as mentioned in bounty wiki. So I am not sure, how this is going to "Reward existing answer". Can anyone please explain what am I missing here?
