Without this fix, UnicodeDecodeError: 'cp932' codec can't decode byte 0xef in position 515: illegal multibyte sequence will occor when pip install

Nice, thanks for the contribution! @hyuma
But according to our check few months ago it will break compatibility with Python 2.7

The best way to fix Windows compatibility and retain Python 2.7 compatibility is by following this sample setup.py file:
https://github.com/pypa/sampleproject/blob/master/setup.py#L8-L24

Would you like to try to add that?

Hi @rizdaprasetya , should we just make release version/branch/tag for backward compatibility?

1. let say, release the un merged branch with version/branch/tag 1.0.0 (compatibility with python 2)
2. and merge the branch and release it with version/branch/tag 2.0.0 and throw everything about python 2 compatibility
3. with this way, it will made easier to track version and compatibility like new version of python or new version of dependencies

also the other reason is python 2 already dead almost 2 years ago. though?

@mashanz correct, thanks for notifying, sorry we haven't review this for a while. Agree with your suggestion, esp. since python 2 is no longer supported officially. we'll use better version tagging to handle such compatibility concerns.

Also if you see any more compatibility issue to latest/current python version feel free to let us know by opening issue/PR. Cheers!

Changed the setup.py implementation to follow official pypa sample project. It should have better compatibility with Windows OS & Python 3 now.

Thanks for your contribution @hyuma & @mashanz! 😃
Will merge now, and release as new version soon. Thanks
