Comment (by ironprogrammer):

 Hi, @nikkigagency -- Thank you for sharing your experience with this
 issue. Based on the example URL provided, it appears to be redirecting
 (HTTP 302) to the "clean" URL. Until the patch is released, the problem
 can be fixed by cleaning up the slug before or after publishing, if you
 catch it. (Per comment:29 "Good to Know", the issue can be harder to spot
 in Chrome.)

 Please note that the underlying issue in the editor that added the special
 character (represented by `%ef%bf%bc`) was addressed separately by
 [https://github.com/WordPress/gutenberg/pull/42321 PR 42321], which looks
 like it shipped with Gutenberg 13.8.

 This ticket's patch adds resiliency to the backend so that the sneaky
 character doesn't get saved to the post's slug in the first place.
