After the latest version update in WordPress I have begun experiencing finding à‚ , commonly in areas where a space bar or return key might have been used or in spots where post was edited, at infrequent times with other added characters added as well. The issue is encountered in older posts from several years ago as well as brand new ones now when reviewing them. The problem appears to be a global one across my site. I will share when the issue is better understood by me and perhaps solved, along with any method used to achieve any corrections.
5/4/2019 I have often edited or created content in rich text formats, then in turn copying an pasting in the visual editor. It may be that any content that was not simple text generated the symbols upon import, and that those were filtered out successfully in older versions of wordpress, but not the new one. I now have a work around that still requires for me to review each post, but the process is amazingly faster. There is a wordpress plug in https://wordpress.org/plugins/tinymce-advanced/ that allows for a search and replace option in visual editing mode. It is available for both classic and Gutenberg. If it is used, each symbol or character set can be found throughtout the whole document, a blank can be entered for the replacement of all, and offenders are quickly deleted from post content.
Of course, now that I got this far, I see there will be a brand new release on May 7th with the announcement “One of the most highly anticipated features for v5.2 is the Site Health Check. This feature adds two new pages in the admin interface to help end users maintain a healthy site through common configuration issues and other elements that go along with having a robust online presence. It also provides a standardized location for developers to add debugging information.” uh uh!
I am also not alone in not being fond of gutenberg, some links to forum discussions: https://wordpress.org/support/plugin/gutenberg/reviews/
At this point my apparent option is to hand edit every post I have written. The most frustrating part of the process is to locate graphics that now seem to have disappeared, a separate issue. Sigh!
