Problem to register User by android accent error

Question

To sending the data by URL to my webservice if I put the path by the example web browser in Chrome:

meuwebservice/inserirusu/á

already by android he has this exit

meuwebservice/inserirusu/%C3%A1

My way

private void inserir(final String edicao) {  edicao = "á"
showProgressDialog();

StringRequest strReq = new StringRequest(Request.Method.GET,
        Const.URL_EDITAR_TRABALHADOR+URLEncoder.encode(edicao, "UTF-8"), new Response.Listener<String>() {

    @Override
    public void onResponse(String response) {
        Log.d(TAG, response.toString());
        if(response.equal("Alterado"){
           hideProgressDialog();
           finish();
        }

    }
}, new Response.ErrorListener() {

    @Override
    public void onErrorResponse(VolleyError error) {
        VolleyLog.d(TAG, "Error: " + error.getMessage());
        hideProgressDialog();

    }
});

// Adding request to request queue
AppController.getInstance().addToRequestQueue(strReq, tag_string_req);

}

The problem is in the

StringRequest strReq = new StringRequest(Request.Method.GET,
            Const.URL_EDITAR_TRABALHADOR+URLEncoder.encode(edicao, "UTF-8"), new Response.Listener<String>()

I have this android output meuwebservice/inserirusu/%C3%A1
