Hi there folks!
Recently i converted a forum from IPB 3.3.x to SMF 2.0.x and now I'm trying to convert the data in the database to UTF-8. In the forum settings I've the Language set to English (Character Set = UTF-8) and everything is being displayed ok, but when I go to the database via phpmyadmin, I see the data displayed like this:

"
This makes me suspect that data isn't in UTF-8 and needs to be converted. If I go to "Maintenance > Database > Convert the database and data to UTF-8" I see this:

But it I try to convert, the data in the database doesn't seem to be fixed and the forum starts displaying invalid characters. I also tried to run the "upgrade.php" and "repairsettings.php", but nothing seems to help.
As you can see, I don't really have a problem at this moment, but I would like to make sure all the data is in UTF-8 in order to prevent future incompatibilities.
Best regards!
