Maybe try _, so if your name is james burt it would be james_burt.
You can try:
bEngine.gameAttributes.h.PlayerDATABASE.h.james_burt.h.InventoryOrder
and see if it returns any item that your character that you are trying to delete has.
If it returns something, make sure he has atleast something in his inventory, you know you have the right char:
(112) ["EquipmentShoes22", "Quest56", "Blank", "Blank", "Blank", "Blank", "Blank"
That is what you are looking for and then do:
delete bEngine.gameAttributes.h.PlayerDATABASE.h.james_burt
And I'm not sure if this works and if you cant find your char with _ as a replacement for space maybe try jamesburt without space.
Otherwise I wouldn't know and you have to find it out yourself.
