允许Django用户名中的希腊字符

Question

我想允许我的用户使用希腊字符进行注册。

我在admin.py文件中添加了以下代码。正则表达式是否正确（regex=r'^[\w\p{Greek}-]+$',）？我想允许希腊语和英语字符

from django.contrib.auth.models import User
from django.contrib.auth.admin import UserAdmin
from django.contrib.auth.forms import UserCreationForm, UserChangeForm

class MyUserCreationForm(UserCreationForm):
  username = forms.RegexField(
    label='Username',
    max_length=30,
    regex=r'^[\w\p{Greek}-]+$',
    help_text = 'Required. 30 characters or fewer. Alphanumeric characters only (letters, digits, hyphens and underscores).',
    error_message = 'This value must contain only letters, numbers, hyphens and underscores.')

class MyUserChangeForm(UserChangeForm):
  username = forms.RegexField(
    label='Username',
    max_length=30,
    regex=r'^[\w\p{Greek}-]+$',
    help_text = 'Required. 30 characters or fewer. Alphanumeric characters only (letters, digits, hyphens and underscores).',
    error_message = 'This value must contain only letters, numbers, hyphens and underscores.')

class MyUserAdmin(UserAdmin):
  form = MyUserChangeForm
  add_form = MyUserCreationForm

admin.site.unregister(User)
admin.site.register(User, MyUserAdmin)
