Global-11: Mandarin Chinese can't type chinese letters?

Dear BB:
When I saw this game I am so glad to find there is an chat channel for my mother tongue. But soon I found I can't type any Chinese letters on it.
I use mozilla firefox16.0.2 for ubuntu ,shockwave flash 11.2.202.0 . Do I use wrong browser? Which one can let me type my mother tongue in this game?
thank you.

Pentory, go to Mozilla.org, and search for the Chinese character set, you probably have just the basic English characters for Firefox installed.

謝謝,Thank you , I will search the Mozilla.org , and hopefully will get this problem solved.

EDIT:I had install and set those Chinese fonts in Mozilla.org web on Firefox browser content one after one , but I can't type them on global-11 chat channel and player mail system in the game. I try stick them from notepad but fail.
I can type Chinese characters easy on forum ,browser command line , so I think maybe the game didn't accept the Chinese fonts.
It's a good game with a deficiency to me. Still encourage BB will developing full Chinese version games in the future.

我已安裝並於火狐瀏覽器偏好設定裡� �一個接一個設定過Mozilla公司網站所有 找到的中文字型,但我仍然沒辦法在第1 1聊天頻道與遊戲玩家郵件系統中使用� ��們。
我試過由剪貼簿軟體轉貼但失敗了。
我能在這個討論區與瀏覽器命令列中� �中文，因此我推想線上工人物語 (the settlers on line) 這個遊戲無法接受中文字體。
對我而言，這是好遊戲裡的一點缺憾� � 我仍期待藍色位元公司(BB=Blue Byte)未來能推出全中文版本的遊戲。
