 Since WordPress 5.9, one of my clients revistabula.com started having an
 akward bug. Sometimes, the character  (%ef%bf%bc) is being automatically
 inserted in the post title after a publish or update using the visual

 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-
 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
 =gws-wiz in Google at whole 2021] and
 =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.
