Unicode category slug cause 404 error

Contribute Bug

AI-generated summary

A 404 error occurs when editing a category with a Unicode slug. To reproduce: change/create a category with a Unicode slug, and attempt to edit the category settings. hawm has found that the error is not related to the unicode usernames setting, as it persists even when enabled. Additionally, setting allowed unicode username characters to \p{Han} does not resolve the issue. hawm discovered that changing the slug generation method to encoded fixes the problem, but this is not a desirable solution as it results in encoded topic URLs.

}

Addition information:

  • Setting unicode usernames is disable
  • Keep happen even enable unicode usernames
  • allowed unicode username characters = \p{Han}
Click the edit button on the category page to go to page 404

Change setting slug generation method to encoded fixed it, but I don’t really want an encoded slug for our topic URL
