Python Django中的用户名配置文件页面url错误

我为用户准备了一个个人资料页面。当他点击用户名时，进入此页面

示例用户名：maxfactor url:domain.com/user/maxfactor

但是如果用户名包含utf-8字符，我将无法访问此用户的配置文件页面

用户名示例：MAXFÜKTOR或LÜLÜY或Küçkzgard

所以问题在于人物的性格。。。当我想转到这个用户名时，浏览器会自动进行错误的重定向，如下所示

domain.com/de/user/MAXF%25c3%259cKTOR

但有趣的是，当我在localhost上尝试它时，效果很好。相同的代码和本地主机的工作方式如下： domain.com/de/user/MAXFÜKTOR/ 而且它是有效的

现在我想到了一些方法，但我不知道怎么做

1-此结构适用于本地主机，但不适用于我的“plesk linux”服务器。我不确定我是否在服务器上安装了丢失的东西

2-我可以在注册成员时阻止这些字符

我希望我能解释这个问题。你可以在下面找到我的代码

url.py

from django.urls import path
from user import views

app_name = "user"

urlpatterns = [
        path('login/', views.loginUser,name="login"),

path('users/', views.view_votes_that_user, name='alluser'),
#path('listusers/', views.filter_user, name='listusers'), kullanıcıları listelemek için

path('register/', views.registerUser, name="register"),
path('update/', views.edit_profile, name='edit_profile'),
path('activate/<uidb64>/<token>/', views.activate, name='activate'),
path('<str:username>/', views.filter_user_core, name='filtercore'),
