Most of Non-English user Asian players are facing a very serious problem since GW2 launches: Some words or all words are missing / unable to display normally in either chat window or the chat bubble in the game despite the encoding of the chat is already Unicode based.
Cause of the problem
As far as I know, GW2 chat server can handle multilingual without any problem. So the cause of the problem will be very likely on the client side. GW2 did displays Korean normally but neither Japanese nor Chinese. It is very similar to my previous experience on other games (Some Korean MMO). I found out that those games are using some Korean font which is not implementing other charset. So I guess the problem in GW2 is the same. GW2 may also use a Korean based font to display chat (Since NCSoft is a Korean company, Anet is very likely need to show demos to their boss)
Suggested Solution
From my experiences, I did changed the font in those games into a well implemented Unicode font and the problem solved. I suggest Anet replace the font using in the chat with some other well developed fonts. Currently, Adobe and Google with some other company developed an open source well implemented font (In Google, it is called Noto Sans CJK. In Adobe, it is called Source Han Sans).
Hope it helps.
