Solved Sunglass-icon displayed after punctuation mark in Descriptions and Categories

Hello, 
After installing Kunena 6.2.0 as Forum-extension in Joomla 5.0.0, I had noticed that there were many black-yellow Sunglass-icons in the text of readymade categories and posts in the Main Forum (out-of-the-box).
I thought it was a pun of a Kunena-developer who created the 'Welcome Visitor' message and the 'Suggestion Box' categories and posts.
But after creating some categories myself with explanatory texts (in Description, and Category Header), I noticed that this sunglass-emoticon (9.png from Kunena) shows up all over the place!
It seems as if the sunglass-icon is stamped (not-by-me) in between the text I had made, after a colon ':',
after a comma ',' a question mark '?' and a dot '.' etc.
My guess is that every punctuation mark in Descriptions or Category Headers is always followed by the sunglass-icon in the frontend (but not in the backend).

How/where can I correct/remove/adjust this exaggerated charade of sunny smileys?

mm strange I don't recognize this
but have you already looked at kunena > Tools > Diagnostics
did they all pass the test?
And maybe reinstall Kunena 6.2.0 Language Package

Hello Leen,
I ran Kunena Diagnostics and all 'TEST PASSED - No issues found!'
I have not installed the Kunena Language package.
Is that necessary?
regards, sthop

would give that a try anyway.

I installed the Kunena Language Pack, and restarted WampServer.
Result: the sunglass-icon  is still overall present in the Kunena Forum Categories and Posts.

Could it have something to do with the fact that I use MariaDB as DBMS? Character map? Collation?

I have looked at all the test sites but I don't see this phenomenon anywhere.
And your smileys from kunena are just the standard installation, nothing has been changed?
this is what the text in my category looks like
