I don’t remember exact date, probably, after WoM, Fatshark patched something about displaying nickname system and it replaced Korean, Japanese, Chinese nickname text with square boxes. (I don’t know other languages status because i’m in East Asia. So I don’t mention other non-English languages)
I hope, at next patch, Fatshark revert this system - displaying non English languages nickname as intact status - like before WoM.
Moreover I want to ask you about adding Korean(and other languages) chat system. Do you have plan to add non-English chat system at future patch? I hope Fatshark add this patch to make players chat with their own languages too.
