 == This report is about assigning keywords to an article.

 **First keyword:** "Gärten" with slug "gaerten" (exists already)

 **Second keyword:** "Garten" with slug "garten" (was not created yet)

 I tried to apply the new keyword "Garten", but once I saved the article,
 the keyword "Gärten" was assigned in the preview. I removed it and tried
 to assign "Garten" once again, but WordPress keeps applying "Gärten" to
 the article, even though **the editor showed "Garten" in the sidebar** (as
 expected).

 I then created the keyword "Garten" with slug "garten" manually in the
 keyword management interface. Now I have both keywords in my database.

 But still, when I try to assign "Gärten" in the editor, WordPress keeps
 changing it to "Garten", once the article is saved and I view the preview.
 The slugs are different (gaerten vs. garten), but it seems like the editor
 confuses the German umlauts in Gärten with Garten.

 I am using the latest WordPress 5.7.2 and the Classic Editor.
