To understand why we want to do this, please refer to this issue on ktmpl repository (a way to have templates for kubernetes):
https://github.com/InQuicker/ktmpl/issues/15
The problem applies only to string used as keys, but given that the emitters right now doesn't differentiate the two cases for string, I think is better to do it also for values instead of introducing branching and/or flag variables (can't think of cleaner solution for now).
