Yelp Dataset Import Issue

I was following the instructions on GitHub - mneedham/yelp-graph-algorithms

I tried to run ```

   return codecs.charmap_decode(input,self.errors,decoding_table)[0]
UnicodeDecodeError: 'charmap' codec can't decode byte 0x8d in position 4383: character maps to <undefined>

i did tried to add  with open("dataset/businessLocations.json", "w",encoding='utf8',errors='ignore') as business_locations_json: 

but still getting the error.
Hope someone can help me
