Hi Patrick, those are alphanumeric chars as well.
A few things to try-
Your % shouldn’t ( theoretically ) be needed here since you’re not using a wildcard match. However I’ve seen weird things lately. I’d try it with and without.
You might also try using a URL-encoded path to see of Webflow matches these properly; /tag/framtidens-%C3%A5terf%C3%B6rs%C3%A4ljare
If WF is really struggling to match, and the starting portion of your URL is unique enough, you could try a wildcard match, e.g.; /tag/framtidens%-(.*) → /tag/framtidens-aterforsaljare
If none of those work I’d contact support and see what they can suggest that’s not covered in the docs.
