UnicodeDecodeError: 'ascii' codec can't decode byte

I was trying the parser in http://piter.io/projects/js2py and I got this error. The input text to parse is included.

I'm getting a similar error. I'm on Windows where I understand the default encoding is cp1252, NOT utf-8. Input is the standard ssf.js Excel formatter (https://raw.githubusercontent.com/SheetJS/ssf/master/ssf.js). Error:

>>> import js2py
>>> js2py.translate_file('ssf.js', 'ssf.py')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\Joe Orost\AppData\Local\Programs\Python\Python37-32\lib\site-packages\js2

    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
UnicodeEncodeError: 'charmap' codec can't encode characters in position 7681-7682: charact
er maps to <undefined>

Avoidance:

>>> js = open('ssf.js', 'r', encoding="utf-8").read()
>>> py = js2py.translate_js(js)
>>> open('ssf.py', 'w', encoding="utf-8").write(py)
