german umlaut in slug produces redirection loop

[mtvary]

Hey,

if you add a german umlaut (for example "ö") to the slug, WordPress sites result in a redirection loop.
Check this: ​https://de.wordpress.org/?ö

(In a perfect world nobody would add an "ö" to the slug, but I'm talking about external links and we can't control that we have to redirect to a 404)

Is there already a fix for this problem?

Hi @mtvary,

Welcome to Trac! My apologies that it took so long for you to receive a response.

The new block editor actually turns the ö character into a regular o. The quick edit interface also performs the same sanitization. However, if I manually insert an ö character into the post slug in the database, I am able to reproduce the redirect.

I made some tests and I could not provoke a redirect loop. Closing the ticket. Feel free to reopen if the issue is still reproducable.
