Key with '/' causing issues

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?
