Hi,
I have a lot of problem with special characters on my service desk instance.
All the characters aren't good when I have the research in confluence and also on the service desk portal. The problem is that customers can see this error.
For information, I have JSD 3.15.1 and Confluence 6.12.0 in french langage by default.
I give you also some screenshots.

Somebody have any suggestions or answer to solve this problem ?
Thank for your help,
