Hi @vasfitugun
This looks like a charset issue. You need to review your DB charset and collation to be sure all is correctly configured. Checking config.inc.php is also important to be sure all match with the DB configuration.
If you don’t have langs with special charsets, I would suggest set it all to “utf8mb4_general_ci” that is wide enough to cover most of the scenarios.
If you make a search in this same forum with “charset collation database” you will get some results.
Those posts are a good starting point:
If you can fix it by your own, let us know and I will try to assist you.
