Django UnicodeDecode Error

Question

First of all I've tried all the ways I could find out on SO and google but none worked, so asking here.

I'm learning djangoand doing a test project. Everything was going well but after creating superuser when I tried to log into admin panel it showed UnicodeDecodeError. I've tried several method but kept getting the error. I'm using django 1.11 on windows 7 32 bit with python 3.
I have created an app students and registered the app. Then ran migrate.

students/models.py

from django.db import models

class Students(models.Model):
    roll = models.IntegerField(primary_key=True)
    name = models.CharField(max_length=200)
    dept = models.CharField(max_length=200)
    inst = models.CharField(max_length=200)

    def __str__(self):
        return self.name + "("+ self.dept + ")"

students/views.py

from django.shortcuts import render
from django.views.generic.base import View
from students.models import Students

class StudentListView(View):
    def get(self,request):
        students = Students.objects.all()
        return render(request,'students/index.html',{'students':students})

urls.py

from django.conf.urls import url
from django.contrib import admin
from students.views import StudentListView

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^students/',StudentListView.as_view()),
]

Can someone help me to solve the issue?

EDIT:
Here is the traceback.

Did you created superuser using any bangla name or something? How did you create the user? Try deleting the user and create new superuser using './manage.py createsuperuser' and login again — ruddra, May 26 '17 at 16:26
@ruddra I created superuser using `python manage.py createsuperuser` command and username is in english. — Tasfia Sharmin, May 27 '17 at 02:41

add these line in the top of your model file and view file

# -*- encoding: utf-8 -*-

from __future__ import unicode_literals

too, set str method equal:

def __str__(self):
   return "(%s)" % self.name

now, try again to run.

Try encoding to utf-8.

# -*- encoding: utf-8 -*-
from __future__ import unicode_literals


def __unicode__(self):
    return u"{} ({})".format(self.name, self.dept)

However, it seems like an environment specific issue.
