Topic with Japanese in URL doesn't redirect if URL doesn't perfectly match

Oh my I spent so much looking into this, and looks like you are using ascii slugs. Please revert back to encoded.

Search the site settings slug generation method in your admin dashboard.

Great, great, thanks! … I change for encoded and everything works now!

Ascii was the one by default … I still don’t understand what differences these make, but at least it works for me. :clap:

Does that mean that when people switch from encoded to ascii it doesn’t regenerate the slugs? If so it seems like the one time process you wrote to clear the slugs wouldn’t work for those cases.

Hello,

The pull did not fix the issue completely. If the slug contains a + sign, it will show the 400 error.
To confirm this, I have switched back to “None” for slug generation, edited the title and removed the + sign from title and switched back to “encoded” it fixed the 400 error.

The scenario is when a title includes a plus sign, it returns 400 error. (There could be other characters that could lead to this. I only tested the + sign)

Thank you

Is that on a topic slug or in a category slug?

A topic slug. Didn’t try on the categories.

The encoded slug generator strips all + signs so I have no idea how you get that:

Just tested locally and they are removed just fine for me.

Perhaps the scenario is different on your local.
My website language is Persian. Can you switch to Persian and then test?

To duplicate this, create a topic with the following subject:
گربه های ایرانی + از نژاد خوبی برخوردار هستند

My slug turns to an unreadable format and returns a 400 error:

Only you are aren’t using the “og” + but a different persian symbol that looks like it? Can you share a string that repros the problem?

I edited my previous reply. Just to confirm it is a + .

That is weird, for me the slug turns into

%DA%AF%D8%B1%D8%A8%D9%87-%D9%87%D8%A7%DB%8C-%D8%A7%DB%8C%D8%B1%D8%A7%D9%86%DB%8C-%D8%A7%D8%B2-%D9%86%DA%98%D8%A7%D8%AF-%D8%AE%D9%88%D8%A8%DB%8C-%D8%A8%D8%B1%D8%AE%D9%88%D8%B1%D8%AF%D8%A7%D8%B1-%D9%87%D8%B3%D8%AA%D9%86%D8%AF

Are you sure you are running latest and refreshed the page?

2 Likes

I am running the latest version.

I am confused now. I created a new topic with the same condition as the topic with corrupt slug. It works just fine. Just like you stated, probably it isn’t the + that is causing the problem.

Please allow me sometime to install a dummy and make some tests. I will update this topic with more information.

Thank you

Did you get that URL from the share button? It was double encoding and I just fixed that on the latest merge.

Oh I see the problem. It only happens with slugs who are above 255 chars and only in 66% of the cases. I will work in a fix tomorrow.

Happens with us too:

eg: Γνωμη για αγορα μπουζουκιου μεσω ιντερνετ και εκτίμηση - Μουσικά Όργανα - Ρεμπέτικο Φόρουμ

Strangely, it only happens when you hit the topic from the “latest” list. When you link to it from another topic, it works just fine.

Same thing, that slug is over 255 chars.

While investigating, I found some categories that can’t load at all.

I found that we get these kind of errors:
