How do I stop this error from happening?

Python

im assuming the error has something to do with the encoding of the data (utf-8/16)

Code:

import os
import json

req = os.popen('curl -H "Authorization: Bearer USRllWyuqyO3KZpKNxKPAuQsMPoMS2qg5o" "https://us.api.blizzard.com/data/wow/search/item?namespace=static-us&name.en_US=Thunderfury&orderby=id&_page=1&access_token=USRllWyuqyO3KZpKNxKPAuQsMPoMS2qg5o"').read()
parse = json.loads(req)
print(json.dumps(parse, indent=2))

Erorr:

<pre>Traceback (most recent call last):
  File "c:\Users\squid\OneDrive\Documents\programming\wowheadapitest.py", line 4, in <module>
    req = os.popen('curl -H "Authorization: Bearer [secret]" "https://us.api.blizzard.com/data/wow/search/item?namespace=static-us&name.en_US=Thunderfury&orderby=id&_page=1&access_token=[secret]"').read()

    return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x8d in position 307: character maps to <undefined>

What I have tried:

Changing the encoding of my files but it doesnt work
