On standard font there arent these squares but when I use Noto Sans font squares are visible - they are also visible in for example dutch translation.
So it looks like it is more font related problem but like I said - im using font that are suggested in this article:
https://www.capitalismlab.com/resources ... game-text/
In attachment font that I use.
EDIT:
I opened latest beta version with my translation and there everything is ok (no squares) but in release version 6.4.17 they are visible.
EDIT2:
The problem is also in the beta version of game, BUT:
when I start new game in english, save it, exit the game and then put translation, open game and load that saved game then there is no problem.
And I noticed that this problem is in all game modes except the challenge game. In challenge game there is no problem even when I start new game in translated game.
