# libfribidi0: needed for Pillow's raqm text shaping engine, used to render player names
# in their original script (e.g. Arabic, Devanagari) on wanted posters instead of
# transliterating them to English. Without it, Pillow's raqm support silently reports as
# unavailable (no install-time error) and only fails the first time a name actually needs it,
# with: KeyError: 'setting text direction, language or font features is not supported
# without libraqm'
apt-get install -y libfribidi0
