I have a need to display a `UITableView` containing a user's account credentials. For this, I'm using `UILabels` in `UITableViewCell`. When I display their password, I'd obviously like to just display a placeholder password character instead of their actual password, similar to a `UITextField` when it's set to secure text entry mode. In fact, I'd like to use the same character as `UITextField` uses, instead of '\*'. 

My question is, what is the character code for the password character the `UITextField` when it's in secure mode?
