因為使用者名稱帶有中文，在indetity Server4中報錯。

解決辦法：

 public IAbpSession AbpSession { get; set; }

        private readonly TenantManager _tenantManager;
        private readonly UserManager _userManager;
        private readonly RoleManager _roleManager;
        private readonly IPasswordHasher<User> _passwordHasher;

        
 
public UserRegistrationManager(
            TenantManager tenantManager,
            UserManager userManager,
            RoleManager roleManager,
            IPasswordHasher<User> passwordHasher)
        {
            _tenantManager = tenantManager;
            _userManager = userManager;
            _roleManager 
 
= roleManager;
            _passwordHasher = passwordHasher;

            _roleManager.RoleValidators.Clear();
            userManager.UserValidators.Clear();
            AbpSession = NullAbpSession.Instance;
        }

_roleManager.RoleValidators.Clear();
userManager.UserValidators.Clear();

加入以上程式碼即可解決中文報錯問題。
