Downlad PDF from URL

Question

I have written this code to download files from URL. It downloaded doc and jpg files. BUt PDF files not downloaded and it shows com.android.volley.ClientError. URL contains this "શુભમ08_23_2016_06_05_33.pdf". Is this problem because of Gujrati characters in url?

This is my Code:

InputStreamVolleyRequest request = new InputStreamVolleyRequest(Request.Method.GET, mURL,
                        new Response.Listener<byte[]>()
                        {
                            @Override
                            public void onResponse(byte[] response) {
                                // TODO handle the response
                                try {
                                    if (response!=null) {
                                        pd.dismiss();
                                        FileOutputStream outputStream;
                                        Features features=new Features(context);

                                        String name=features.findName(mURL);;//<FILE_NAME_WITH_EXTENSION e.g reference.txt>
                                        File sdCard = Environment.getExternalStorageDirectory();
                                        File dir = new File (sdCard.getAbsolutePath() + "/AIO");
                                        if (!dir.isDirectory())
                                        {
                                            dir.mkdirs();
                                        }

                                        FileOutputStream f = new FileOutputStream(file);
                                        //f=context.openFileOutput(name, Context.MODE_PRIVATE);
                                        f.write(response);
                                        f.close();
