Arduino Leonardo

Hello I'm using my Arduino Leonardo, but I'm French and I can't print these letters :


Even when I try :;;

I installed french library : GitHub - martin-leo/KeyboardAzertyFr

So I don't know what to do and I am lost between ASCII, hexadecimal and all these stupid stuff.
I just wanted a working card not to learn all the ASCII table !
So please help me, there is no tutorial in french wich worked for me.

Thank you in advance,
