Buggy sorting in Greek

Greek alphabet sorting seems a little bit wonky.

It goes well but words that start from Π (Pi) go to the end of the list for some reason.
(Also words with acute accent are out of order)

PHP sorting seems okay, so it must be a kirby thing. :face_with_monocle:


<h1><?= $page->title() ?></h1>

	<?php foreach ($page->people()->toStructure()->sort('name', 'asc') as $p) : ?>
		<li><?= $p->name() ?></li>
	<?php endforeach ?>

$names = array("Ανέστης", "Βασίλης", "Γιάννης", "Zelda", "Δημήτρης", "Ελένη", "Ζωή", "Ηλίας", "Θωμάς",  "Dean", "Ιωάννα", "Κατερίνα", "Cindy", "Λουκάς", "Μαρία", "Νίκος", "Ξανθή", "Ορφέας", "Παναγιώτης", "Ραφαήλ", "Amanda", "Σοφία", "Τάσος", "Υπατία", "Φίλιππος", "Χρήστος", "Ψαρρής", "Ωραία", "Bill");
echo '<pre>'; print_r($names); echo '</pre>';

For someone that doesn’t understand Greek, ending with Ω seems about right. So I think I’m unable to reproduce your issue. Maybe add some details: what Kirby version are you using? Is this the exact code and content you’re running, or does running this exact code actually show the problem on your machine?


First of all, thanks for taking the time to replicate my obscure issue.

Once again I didn’t even consider to try it on a live server, where the behavior is the one you describe. So thanks again!

This means that for some reason Valet does something iffy, which I don’t have the skills or the patience to investigate further, especially since on the live site it works as intended.

I’ll mark as solved, mainly because it’s not a deal breaker and this could act as a cautionary tale for others.

All the best,

You may want to look into your locale settings. Kirby uses locale-based sorting, so setting your locale to Greek explicitly should make it also work locally. You can also set the locale settings globally in your php.ini. Please note that the exact syntax depends on your operating system. E.g. it could be el_GR.utf-8 or el_GR.UTF8.

Out of curiosity… does it? When first answering here I thought so too, and the PHP docs are not very specific, but now I think SORT_REGULAR (what kirby uses by default) doesn’t actually read any kind of locale settings. I mean there is SORT_LOCALE_STRING that explicitly does that, and SORT_REGULAR sorts using the “normal” comparison operators (>, <, <=>, etc.).

Anyway, Kirby accepts a third parameter in sortBy for the sorting method. @relay could use that (with SORT_LOCALE_STRING and the locale settings) to get a more accurate sorting, if the hosting company actually has a greek locale installed (that should also solve the “acute accent problem”).

Thanks for pointing that out. Actually the default in the code is SORT_NATURAL | SORT_FLAG_CASE, but that also shouldn‘t take locales into account. It‘s weird that the sorting without locales differs between installations.

In any case, I‘ve updated the sorting recipe with up-to-date information.

I have a slight suspicion that there’s an invisible difference in the data between staging and production in this case.
Like, the problematic Π might actually not be a Greek pi (U+03C0), but maybe a Coptic pi (Ⲡ: U+2CA0) or a Cyrillic pe (П: U+041F) or something like that.
