Database problem

After update to 3.4.1.

It changed database so third party City name, contact last name, note(public), note(private) does no longer support our local language letters.

Hi katas,

Can you be more specific?

Check that fields into database for example field “town” into llx_societe have format utf8.
You may see that using a database browser tool like phpmyadmin.

Thanks, fixed it. But data has been affected already.

All or only those changes are made?
