This is a bug or feature ?

Hello everyone who reads this topic   

Helping one man solve his problem with the redirects, I was faced with the problem...
let's say I have this small system routing:

PHP Code:

$routes->group('{locale}', function($routes) {
    // Test #1 page
    $routes->add('FirstTest', 'TestController::test_1');
    // Test #2 page
    $routes->add('SecondTest', 'TestController::test_2', ['as' => 'Test_2']);
}); 


and in the method "test_1" spelled out the function "return redirect()->route('Test_2')",

then when you go to this route, it redirects to "TestController::test_2" and in the place of the name of the locale in the url is this entry: "%7Blocale%7D" and segmet "/SecondTest"

Q: is This recording supposed to be like this "%7Blocale%7D", or should it be the localization we were originally in ?

I would change this world, but God doesn't give me the source.
