Error in accentuated character (encoding mismatch ?)

Hi again,

I tried to launch the game with a different language (French) and all accentuated characters are wrongly displayed as it's often the case with encoding mismatch.

step to reproduce
1° pick a different language (French) in knossos
2° start a training campaign, press F2 and see all those characters being wrongly displayed

configuration
fso: all versions I could try (to 3.8.0 to nightly)
os: mac os 10.14.6

Djamé
ps: let me know if bug reports are welcome even for a niche platform (mac os, French)
