T5: Can Grid support custom label in UTF-8 encoding?

[yuan gogo]

I have UserList.java UserList.tml UserList.properties.
In UserList I used a grid to show all registerd users and I'd like to custom
the Grid header.
So I defined some column titles in UserList.properties (of course, in
Chinese and the file is UTF-8 encoding), but it can not be displayed
correctly. English chars has no such problems.

Anybody helps?

TIA and Best regards!
