Ember.js Query Params decoding

I'm working with some params in the url trying to make similar to google maps, but ember keep encoding my url.

I already tried to use serializeQueryParam and deserializeQueryParam to somehow show special character but I had no lucky.

Ember place my url like this:

/?at=-22.9553706%2C-43.1948505&z=18

But I want him to show the entities...
