BotDetect Captcha имеет ошибку с японскими символами (laravel-captcha)

Я использую Laravel 5.5, это происходит с символами Японии (неопределенное смещение: -1 в /CaptchaInclude.php) в последние дни (я ничего не менял, все было оштрафовано на несколько месяцев).

Причина этой проблемы НЕ моя плохая, поэтому, пожалуйста, «НЕ МАРКИРУЙТЕ» это как «дублирующую» проблему, я не нашел ответа на свой вопрос.

Это моя кодировка:

public function login(Request $request)
{
// Delete old session (error validation)
$request->session()->forget('wrong_captcha');
$request->session()->forget('wrong_fivetimes');

$throttler = Throttle::get($request, env('LOGIN_TIMES'), env('WAITING_TIME'));
// login fail > 5 times
if(count($throttler) > 5) {
// message input invalid over 5 times
$request->session()->put('wrong_fivetimes', 'Input wrong 5 times!');
return redirect()->back()->withInput();
}

// Get data from 'Login form'
$email = filter_var($request['email'], FILTER_SANITIZE_STRING);
$password = filter_var($request['password'], FILTER_SANITIZE_STRING);
$captcha_code = filter_var($request['captcha_code'], FILTER_SANITIZE_STRING);
$isHuman = captcha_validate($captcha_code);

// Validate the form data
$this->validate($request, [
'email'   => 'required|email|max:255',
'password' => 'required|min:6|max:100',
'captcha_code' => 'required'
]);

// check count fail times
if(count($throttler) <= 5) {
// admin input captcha code equal to generated captcha system
if ($isHuman) {
// Attempt to log the user in
if (Auth::guard('admin')->attempt(['email' => $email, 'password' => $password])) {
Throttle::clear($request);

// if successful, then redirect to their intended location
return redirect()->intended('admin/dashboard');
}
// count up (login fail times)
Throttle::hit($request);

// if unsuccessful, then redirect back to the login with the form data
return redirect()->back()->withInput($request->only('email'));
}
// count up (login fail times)
Throttle::hit($request);

// message input captcha code is wrong
$request->session()->put('wrong_captcha', 'Input captcha is wrong!');
return redirect()->back()->withInput();
}
}

И это моя проблема:
