RSS Feed Encoding Problem – WordPress Development Stack Exchange

The RSS feed I need help with:
The page with the feed displaying strange characters:

In addition, all my plugins are currently disabled.

I am having an encoding problem with my RSS feed only. The characters "" and others continue to encode like this & # 8217; and [ &#8230 ;] (it was necessary to put spaces to show the code) This is not the case on the blog, the coding remains normal. This occurs in the title and description. MySQL tables are encoded correctly and my wp-config.php file is set to utf-8.

No suggestion?
