In addition to what I wrote in the previous message, I create a txt file with Persian language in windows and when I saved it selected UTF-8 and uploaded it in the chat, but when the file was uploaded and I opened it, it was displayed as follows:

Then I tested another solution. I create a txt file with NOTEPAD++ and when i saved it as UTF-8 BOM , the problem was solved:

Can you change the system so that it uploads and displays any UTF-8 code correctly?

This is my problem because of changing the WordPress login URL.

I removed the code from the functions.php and the problem was solved.

Then I tried another solution, which was to create a PHP file in wp-content/mu-plugins and put the following code in it, but the same redirect problem still occurred:

<?php
add_action('login_init', 'custom_login_url_protect');
function custom_login_url_protect() {
    $secret_key = 'MY-CUSTOM-URL';
    if (isset($_GET['action']) && $_GET['action'] === 'logout') {
        return;
    }
    $allowed_actions = ['lostpassword', 'rp', 'resetpass', 'register', 'postpass'];
    if (isset($_GET['action']) && in_array($_GET['action'], $allowed_actions, true)) {
        return;
    }
    $is_valid_url  = isset($_GET[$secret_key]);
    $is_valid_post = isset($_POST['secret_login_field']) && $_POST['secret_login_field'] === '1';

    if (!$is_valid_url && !$is_valid_post) {
        wp_redirect(home_url());
        exit;
    }
}
add_action('login_form', 'add_secret_field_to_login');
function add_secret_field_to_login() {
    echo '<input type="hidden" name="secret_login_field" value="1" />';
}

By default, the plugin displays country flags at the bottom or top of the website, as shown in the image below.

Is there a shortcode or php code that allows me to display country flags in the desired location?
