I'll be submitting a pull request that solves this issue in a minute. The 'Country' class, found in in 'entity.py', inherits its 'get' method from the 'Entity' class. I was able to solve this issue with seemingly no averse effects by adding in 'id_value = id_value.lower()' on line 114 of 'entity.py', thereby converting all potentially malicious inputs to be lowercase, as the functionalities of the Country class expect them to be.
