How to Force a language?

Hi, i installed the GOG version of Obscure that is in english.
I copied the files taken from my italian version of steam (that doesn’t works…) and overvwritten the original in folder game.
If i launch the game directly from the .exe is in Italian, but if i try to launch it from lutris it stars in english…
The same if i create a shortcut in steam.


Could you guys help me?
