XF 2.3 2.3.3: German Umlauts (ä, ö, ü) are no longer resolved in URLs

[rike-online]

Hello everyone,

I have now upgraded from XenForo 2.2 to 2.3 (currently to 2.3.3). Since there were major changes, I carried out an intensive check for errors (especially in my adapted design) after the upgrade. I noticed that despite activating "Use fully friendly URLs" my umlauts in the URLs are no longer resolved:

From the thread title "Wir bauen um für Euch!" will no longer be

h**ps://www.xyz.de/forum/themen/wir-bauen-um-fuer-euch.123456/

rather

h**ps://www.xyz.de/forum/themen/wir-bauen-um-fur-euch.123456/

I first looked in the settings, there used to be an option "Romanization" or something similar, but it no longer exists. Then by chance I found a thread on xenforo.com that describes the same problem for another user. The solution here is said to have been that Beta 7 (I think) no longer contained this error. I didn't even have the betas installed. Maybe the bug is now back in the release (it all already existed).

Then I found a thread in which a user with the same problem points out that PHP 8.2 has this problem. contained an error. I was using version 8.2 until yesterday and then updated to PHP 8.3... unfortunately without success.

Then I looked at my .htaccess, which I had been using for several years without any problems. I didn't notice anything here either.

Addendum: I also deactivated all addons --> no success. Another note: My forum has been running for 20 years (first vBulletin, then XenForo), we never had any problems after the initial setting for umlauts or SEO-friendly URLs...

Does anyone have an idea or have the same problem with 2.3.3?
I don't know what to do here anymore...

Thanks for your tips,
rike

Do you have the PHP intl extension enabled? It should provide more robust/accurate transliteration in XF 2.3+. Also, the romanization option still exists.

For more robust/accurate transliteration in XF 2.3+, we recommend installing the intl extension.

Thanks, Jeremy for your quick reply!

Then my host has to install it on my server.

Where can I find the option?

Also make sure your default language has the right locale set. If you still have issues afterwards I can take a second look.

Yes, the extension is installed:

Ah, there it is:

...is enabled.

Hmm, you might try replacing line 75 of src/XF/Util/Str.php with:

                if (strpos(($rule->id ?? ''), 'de-ASCII') === 0)

This fixes the behavior in my testing, will sort that for 2.3.4.

How can I ensure this? Where to set? Server-config? XenForo-config?

Select your language at Control panel > Appearance > Languages and check the Locale setting.

I'm on a Managed Server, so I have to ask my host for it.

Yeahhhhhh, that's it!!!!! This line solves my problem!

Great support, Jeremy, thank you very much for that!

Thanks for bringing it to our attention

You might want to consider releasing a patch for 2.3.3 as this issue could affect quite a lot of URLs on german forums and thus cause a significant amount of redirects back and forth which search engines might not like that much.
