Using gettext to translate wp-login.php can't translate `Back to` into other language

Question

I created a plugin to translate text of wp-login.php page into Arabic, every thing translated well except Back to which appear at the bottom of login form, I can't catch it to translate into Arabic

My site name called Foodonia, and I want to translate ← Back to Foodonia to العودة إلى فودنيا , I tried each one of below:

← Back to Foodonia
Back to
Back to Foodonia
← Back to Foodonia
← Back to

here is my code

function my_custom_login_label( $translated_text, $text, $domain ) {
    if (in_array( $GLOBALS['pagenow'], array( 'wp-login.php', 'wp-register.php' ) )) { 
        if ($translated_text === 'Username') $translated_text = 'اسم المستخدم';
        if ($translated_text === 'Password') $translated_text = 'كلمة المرور';
        if ($translated_text === '← Back to Foodonia') $translated_text = '← العودة إلى فودنيا';

    return $translated_text;
  }
}
add_filter( 'gettext', 'my_custom_login_label', 20, 3 );

My site URL: http://foodonia.com (changing language between English and Arabic using site nav menu will effect the login language)

Answer 1

The correct string is '← Back to %s'. The site name is inserted after the translation.

See the function login_footer() for details.
