Single Quotes in Patentsview Locations

I didn't see this mentioned in the api documentation: you need to double up single quotes in a city etc. No rows were returned when there was only one single quote.

This page is sending in a get request to the /locations endpoint with the following parameters:

q={"_contains":{"location_city":"''"}}
&f=["location_total_num_patents", "location_state", "location_country", "location_latitude", "location_longitude", "location_city"]
&s=[{"location_state":"desc"}]


Hover over a pin to see the city name or click on a pin to see the latitude, longitude and number of patents the location has.
