NERDTree goes whack in tmux session as in the picture. The same problem exists when windows are split. But now i am using powerline This time the Vim status goes whack(in the picture see the middle portion of the status line) in tmux. What is wrong?

I figured the solution after a long time, looking at a dotfile repo in github. It was just a single line of code that made the communication between Vim and Tmux smooth.
In the .tmux.conf file, add this line
set-window-option -g utf8 on
