Unicode slug dose not work after deploying in iis8

Question

I need help to solve my problem, I deployed a django web app in iis 8 that contains Persian slug, in development everything ok but when I deployed the app in iis 8, the app urls that contains Persian Unicode characters are not working.

urls.py:

from . import settings
from django.conf.urls.static import static
from django.contrib import admin
from django.urls import path, include, register_converter
from .views import *
from django.urls.converters import SlugConverter


class CustomSlugConverter(SlugConverter):
    regex = '[-\w]+'


register_converter(CustomSlugConverter, 'custom_slug')

urlpatterns = [
    path('admin/', admin.site.urls),
    path('dashboard/', include('tour.urls')),
    path('ckeditor/', include('ckeditor_uploader.urls')),
    path('', IndexPage, name='index-page'),
    path('tour/<int:id>/custom_slug:Slug>', TourDetail, name='tour-detail'),
    path('hotels/<int:id>/<custom_slug:Slug>', HotelDetail, name='hotel-detail')
]

models.py:

Slug = models.SlugField(max_length=200, unique=True, null=False, verbose_name='لینک سئو')

All URLs with English slug work but only Unicode slug dose not work in deployment, in development everything okay.
