Utf8 problem ?

Hello,

New user, I’ve configured Kodi with one mariadb database on a linux machine.
My library is declared with “smb://192.168.2.13/basilette-salon/” path and works great.

Problem is : CU lrc lyrics does not find local files containing special characters (accents)
And title should be “Petite Angèle”

When finding and displaying local lyrics ( a title without accents ), accents inside lyrics are ok :

Problem disappears with local path (/basilette-salon instead of smb:// etc)
So this could be a samba utf8 problem, but files display correctly with my browser :

Of course, all my txt files containing lyrics have same syntax example : Petite Angèle.flac -> Petite Angèle.txt

Any idea ?
Thanks in advance.
