What happened?

When trying to use translation files with particular names (like design, services), CodeIgniter does not purposefully load the requested files. Every other name works fine.

I also noticed it doesn't matter if the filename is only that word: if the filename starts with that word (example: mservices), it still doesn't load. However, if the filename starts with that word, but ends with a different letter (example: designp), it works. Moreover, if the filename starts with that word, but ends with a letter same as the last letter of the "word" (example: servicess), it doesn't work.

Steps to Reproduce

Example: app/Language/it/services.php

<?php
return [
    "aaa"  => "bbb",
];
?>

(Copy and paste to app/Language/en/services.php, aka the files are the same inside.)

Try to load services.aaa, you'll see it doesn't work:

<?= lang('services.aaa') ?>

Expected Output

Expected output is working translation files without the need for some kind of "filter".

Could not reproduce. Please pay attention to the details and follow the naming convention described in the user guide: https://codeigniter.com/user_guide/outgoing/localization.html#language-localization

This is how I tested it on the current develop:

//app/Language/en/Services.php
<?php
return [
    "aaa" => "bbb",
];

dd(lang('Services.aaa'));
// returns: lang(...) string (3) "bbb"

@michalsn, have you tried with a lowercase name? I swear I'm not crazy. I have other translation files and they work fine, only some names (like the ones in the issue above) don't work.

Yes, still no issues. Checked on macOS and Linux.

Have you tried it on a fresh install? With only 1 file added: app/Language/en/Services.php and a call in the controller to lang('Services.aaa')?
