Windows html and snapshot filename path problems

[dofine]

Windows 7 with Python 2.7, with the latest pyecharts and pyecharts-snapshot from github.

1. Using forward slash in path or any path generated with os.path module won't work. Change it to back slash works.
2. Chinses name in the full absolute file path won't work.

radar.render("pics\\index.html")
make_a_snapshot("pics\\index.html", "pics\\echarts_radar3.png")

Result:

\lib\site-packages\pyecharts_snapshot\main.py", line 64, in make_a_snapshot
    base64_imagedata = content.split(',')[1]
IndexError: list index out of range

Do you have phantomjs installed?

Reproduced. Finally, I found a windows PC to reproduce it.
