Estimated delivery text issues (with other languages)

There are known issues with the texts of the Estimated delivery, showing strange symbols like question marks.

The days of the week are printed with PHP’s `strftime` function, so this is likely happening because the server’s PHP locale is not loading the most common locale module.

Luckily there’s a whole lot of awesome people online and this article helped me figure it out.

What you’ll need to do is to add this code in your child theme’s functions.php file:

add_filter('reycore/woocommerce/estimated_delivery', function( $settings ){
  $settings['locale'] = 'fr_FR.UTF-8';
  return $settings;
});

As you can see instead of the most common ‘fr_FR’ locale, it’s using and extra UTF-8 declaration.
