Company API filters return empty results when special characters are used

When using the Company API with name filter and the checked value has special characters like ' or & the results are empty. I've double checked and company I'm looking for exists.

I've tried encoding the name but still receive an empty result. For example:

Raw string: Stephan D'Maria
Encoded string: Stephan%20D%27Maria

Has anyone experienced similar issues and provide information how to approach the problem?
