How can I send unicode characters by using tmux command?

Question

Here is my tmux command

tmux send-key -t session:window.pane say 安安 enter

but the result is

root@debian:~# say

(There is no "安安", unicode characters.)

How can I send the non-ASCII Characters???

(my tmux version is 1.8)

This is a known bug in tmux 1.8 and earlier. It is fixed in the SVN version of tmux. See this thread for more information: https://www.mail-archive.com/tmux-users@lists.sourceforge.net/msg04478.html
