I will start by examining the uploaded files to identify any issues with data range misrepresentation. Initially, there was a decoding error with one file using 'utf-8', likely due to a different encoding. I will try another encoding to resolve this. The files have been successfully read, so I will now check for any data range misrepresentation issues. Based on the analysis, no such issues were found. If you have specific criteria or keywords to search for, please let me know for further assistance.
