Characters printed as question marks('?') only under Snap

I’v created a snap that run a java cli program, the program prints to the terminal the following chars: █ ▀ ▄

Only under the snap it print ‘?’ (question marks) instead of this chars .

Anyone knows why? @ogra @ijohnson @mborzecki @jamesh

Thanks!

Additionally, when I’m running snap run --shell mysnap And trying to run the chars it get them as escaped codes:

root@ubuntu1804-template:/home/myuser# █ ▀ ▄
bash: $'\342\226\210': command not found

it happens only under snap, when I’m running it in my default shell I’m getting:

root@ubuntu1804-template:~# █ ▀ ▄
█: command not found

Solved by adding to the snapcraft yaml:

apps:
  my-app:
    environment:
      LANG: C.UTF-8
      LC_ALL: C.UTF-8
