python output issue with Chinese characters

While I using atom to write python 3.4 program, I try to print a string containing Chinese characters.
But the output show "我的名字是" as "�ҵ�������".
I run the script in the terminal and everything is fine.
So I think it might be something wrong with encoding or font.
I try to use # -_-coding:utf-8 -_ ,but it doesn't work.
So I post here to seek helps.
I'm using atom 1.0.19 on Windows 8.1
