UNSOLVED Display emoji in calendar module

[Jonisos]

Hello all,
my mirror is all setup, hardware and software wise. Only problem left: My calendar module displays all emojis as squares. Since I really like just having an emoji instead of reading a word I would appreciate any suggestions towards this problem.

I already tried downloading an “emoji-font.tff”, placed it in the /usr/share/fonts folder of the RP and changed all font-family in the main.css to the “emoji-font” name. The font appeared to be different but still: no emojis displayed.

Thanks ahead.
