Translation files not importing correctly

I’m following this tutorial for implementing translations into my game. While importing though, I get this block of error messages:

The csv I have in the file system contains this data:

https://lemmy.blahaj.zone/pictrs/image/f60966d4-564e-469c-8d1a-86be571f6664.png

and it uses UTF 16. It seems as if Godot expects a UTF 8 file for some reason, even though these files don’t support speciala characters (which are used heavily in different languages). Does someone know what is going on here?
