If `$locale` is invalid, the return value is actually the value of `$locale`, not `NULL` or `FALSE` as you might expect.
(If `$in_locale` is invalid, but `$locale` is valid, the return value is the language name in the default locale.)

To display special characters correctly in a web browser, it's a good idea to decode the result data with utf8_decode:
<?php
echo utf8_decode(Locale::getDisplayLanguage('sl-Latn-IT-nedis', 'fr'));
echo utf8_decode(Locale::getDisplayLanguage('sl-Latn-IT-nedis', 'pt-BR'));
?>
