Accents in subtitles doesn't work well

On Mac, with VLC 3.0.3 (since the 3.0 version), when I load a .srt subtitle in the video, accents aren't working well (it's french accents). There isn't the black border like other letters and it's for every french accents (é ; è ; â ; à ...).

I think the problem isn't the file, because I have this problem for every file since the 3.0 version, with .srt files.
