I have come across a situation in some of my data where a key has the / character in it. I want to dig into this further but it seems like this could be a blocker with the current code.
EG:

{ parent: 'Furniture|Bookcases|Bush', 
    label: 'Bush Andora Bookcase, Maple/Graphite Gray Finish', 
    key: 'Furniture|Bookcases|Bush|Bush Andora Bookcase, Maple/Graphite Gray Finish', 
   }

Any thoughts or recommendations for how to work around this?
