This is most often due to the type of encoding you are using in your database. There’s not a whole lot I can do to remedy that, but you should reach out to your web host to ask them about it.
You can see docs on this here:

There is the ability to force that via your wp-config.php file, but it can be a bit complicated for sites that already have a lot of content. See here:

Thank you for your reply Matt
No worries, keep me posted on your progress.
