Ojet uses encoded URL when params are used in router.go

When I use router.go in Ojet like below

self.args.router.go({ path: serverData.nextViewUrl, params: { c: serverData.sessionId } });

I get the following URL

?ojr=start_form%3Bc%3D63A4CC7E647582AF7E6C634B7FBF82F2

Above is the encoded URL. How do I get the correct decoded url by default in Ojet like below:

?ojr=start_form&c=D63A4CC7E647582AF7E6C634B7FBF82F2

Additional info:
Following is my router setup:

// Router setup
      let router = new CoreRouter(navData, {
        urlAdapter: new UrlParamAdapter()
      });
      router.sync();

      this.moduleAdapter = new ModuleRouterAdapter(router);

      this.selection = new KnockoutRouterAdapter(router);

      // Setup the navDataProvider with the routes, excluding the first redirected
      // route.
      this.navDataProvider = new ArrayDataProvider(navData.slice(1), { keyAttributes: "path" });

I am using the latest OJet v11
