(Myth/Auth)how to input username in Japanese

Thanks for everything.
I was able to add login functionality to an existing app using Myth/Auth, but the next step is that Japanese cannot be used for user names. Can this be solved by customizing Myth/Auth?

I am now trying the following commands.

PHP Code:

php spark auth:publish
Publish Controller? [y, n]: y
  Created: Controllers/AuthController.php 
Publish Models? [y, n]: y
  Created: Models/LoginModel.php
  Created: Models/UserModel.php 


If I can exclude `alpha_numeric_space`, you can probably input Japanese, but it hasn't worked yet.

thanks kenjis

I have debugged the login page.
In auth:publish, for some reason it is reading the vendor side file even though I brought the file. Is there some configuration?

Add routes in app/Config/routes.php and check.
$ php spark routes

thanks, kenjis
I was able to override it by simply changing the direction of the same route in app/Config/Routes.php

PHP Code:

// app/Config/Routes.php
$routes->get('register', 'AuthController::register'); 


PHP Code:

// php spark routes

| GET    | register | \App\Controllers\AuthController::register |　　　←OK！

| GET    | login   | \Myth\Auth\Controllers\AuthController::login   |
| GET    | logout   | \Myth\Auth\Controllers\AuthController::logout |
