Sometimes, the character  (%ef%bf%bc) is being automatically inserted in the post title after a publish or update using the visual editor. He uses an environment different from mine, so I couldn't reproduce the issue myself, he uses Chrome and Mac. As such, I don't know if this is a bug from 5.9 itself or from a plugin. In any case, I've fixed the issue with a simple string replace at `wp_insert_post_data` action. But yesterday, one of the blogs I follow, published an article containing the same bug: https://macmagazine.com.br/post/2022/02/07/promocoes-na-app-store-swim-out-911-operator-navidys-dislexia-spelling-help-e-mais%ef%bf%bc/ . It's a Mac centered blog, so I suppose they also use Mac for editing (Ps.: not sure if they will fix it) I've then searched on Google for this issue, and it have a few complains from a couple of years ago, related with Yoast SEO plugin. But none recent. I've then searched for that symbol in *.wordpress.* domains [https://www.google.com/search?q=%25ef%25bf%25bc%2F+site%3A*.wordpress.*&biw=1325&bih=1311&tbs=cdr%3A1%2Ccd_min%3A1%2F1%2F2021%2Ccd_max%3A1%2F1%2F2021&ei=u70CYoqZBMy45OUP6t-6cA&ved=0ahUKEwjK4r6c5fD1AhVMHLkGHeqvDg4Q4dUDCA4&uact=5&oq=%25ef%25bf%25bc%2F+site%3A*.wordpress.*&gs_lcp=Cgdnd3Mtd2l6EANKBAhBGAFKBAhGGABQAFgAYLoEaAFwAHgAgAEAiAEAkgEAmAEAwAEB&sclient=gws-wiz in Google at whole 2021] and [https://www.google.com/search?q=%25ef%25bf%25bc/+site:*.wordpress.*&tbs=qdr:w&source=lnt&sa=X&ved=2ahUKEwi6g-We5fD1AhXeFbkGHVFQBzYQpwV6BAgCEBw&biw=1325&bih=1311&dpr=1 for the last weeks]... no results in 2021, 3 pages of results for last week. Anyone else having this issue or can better test on a Mac trying to reproduce the issue? Also, not sure if this should be filled at Gutenberg, as I'm not sure if the issue happens in old editor as well." defect (bug) closed normal 6.1 Permalinks 5.9 normal fixed has-testing-info has-screenshots has-patch needs-testing
