My zimbra edition is zimbra509 . I use the command as follows:

aa admin adminpwd
sm admin
s -t message admin

If message subject in chinese, I will get it in mess code . The search result is :
Id Type From Subject Date
---- ---- -------------------- ----------------------------------------- ------------
1. 285 mess admin 鍝堝搱鍟婂搱鍝? 09/09/08 00:08

I want to know how does this happened , and how to make the subject display correctly if it is chinese ?
