Unicode File Python Error in compile_b4w.py

Hi,
When I compile an application, the process fails due to a Unicode read error in compile_b4w.py. I am running B4W 17.06.

I have also seen this behavior in 17.04, but I was waiting for 17.06 to test because Ivan suggested a fix for a related issue was coming in 17.06.

If anyone else is having this issue, change line 434 in compile_b4w.py
from:
f = open(abs_path)
to:
f = open(abs_path,encoding="UTF8")

per Ivan's suggestion in the other thread.

I am running Windows 10 and use Notepad++ as my text editor.

Here is the error message from python:

Traceback (most recent call last):

Thanks,
