All Chinese, Japanese etc. characters are displayed as squares, see screenshot (Waterfox vs Chrome, not sure why Waterfox got some shown properly).
I tried re-installing pango, and changing default system font, neither helped. Input characters with fcitx show up fine in all app that I tested, even in gnome-terminal.

Running Antergos 17.5 GNOME + i3, default font: Fira Code

Any advise and suggestion is much appreciated, thanks!
