unknown char

Hello, Since the last patch 2.0.3, I can't load any save or start a new game. During the chargement processus a window pop up with the message "Unknown char:"

I am on linux I already use the linuxstable version (before that the game didn't start and freeze on black screen)

Player.log

Config : HP Proliant 

2 x Xéon X5450

16 GB RAM DDR2 ECC

GPU Geforce GT 610

That worked before the last update

Help ! 

Thank you
