I tried the plugin on a site running bbPress. Smileys were replaced as expected in normal WordPress posts, pages, and comments. But in bbPress posts it left a broken image.
Looking at the markup in a bbPress post without the plugin, smilies appear something like this:
<img src="https://example.com/wp-includes/images/smilies/icon_smile.gif" alt=":)" class="wp-smiley">
With the plugin active, in a bbPress post the beginning of the file name and the file extension is removed. Everything else stays the same:
<img src="https://example.com/wp-includes/images/smilies/smile" alt=":)" class="wp-smiley">
In the rest of WordPress, the plugin replaces the smiley with the new markup:
<span class="wp-smiley emoji emoji-smile" title=":)">:)</span>
