utf-8' codec can't decode bytes in position 31608-31609

[Uziel9999]

I am using Jupyter notebook to run the script. I used the example from this site, but with an actual company website. This is on windows 10 using the latest version of Anaconda.

What am I doing incorrectly?

Input:
from seoanalyzer import analyze
site = 'http://www.site.com'
sitemap = None
output = analyze(site, sitemap)
print(output)

Results:

UnicodeDecodeError Traceback (most recent call last)

----> 6 output = analyze(site, sitemap)
7 print(output)
