Is there a way to make accent insensitive queries?

I have a page where a user can type a city name and it shows all the stores in the city. The problem I’m having is that I have cities on my database with accents like “Maringá” and if the user types “Maringa”, without the accent, the query does not return “Maringá”. How can I show the results regardless if the user types the city name with or without the accent?
