TensorFlow: use gfile.FastGfile() method can't not read a file with its path include Chinese characters - unicode

Question

I want to read use gfile.FastGFile(image_path, 'rb').read() to read a picture and use it as the input of my project, and I use the directory name as the lable of these pictures which are include in the directory, when the directory name is in English, my code works fine, but when the directory name is in Chinese, it throws this Error:
Traceback (most recent call last):
File "F:/pythonWS/imageFilter/jpegFileJudge.py", line 27, in <module>

my test code is :
# -*- coding: utf-8 -*-
import glob
import os
import random
import numpy as np
import tensorflow as tf
from tensorflow.python.platform import gfile
image_folder='F:/vsWorkspace/pics/test'
os.chdir(image_folder)
count=0
for each in os.listdir(image_folder):
each=os.path.abspath(each)
os.chdir(each)
for image_path in os.listdir(each):
image_path = os.path.abspath(image_path)
print(image_path)
image_data = gfile.FastGFile(image_path, 'rb').read()
count += 1
os.chdir(image_folder)
My envirorment is Windows7 x64, python 3.5.3 and TensorFlow 1.0, How can I solve this problem?
By the way,I have to use Chinese directories' name use my pictures lables.
