Modified and Fixed Errors of Non-UTF Decoding
HTTrack Works Fine in downloading without this bug (Need to Set Settings
Correctly) ... better than Commercial Programs Like WebZip,IDM-Grabber,Offline
Explorer and Free - Cyotek WebCopy
(Also Images in <https://www.editpadpro.com/> wont load -
<https://www.editpadpro.com//img/icon100.png> wont link)(Is there any way to
delete/modify Reply)

Heres is revised Working Python Code (Always can Ask ChatGPT To Improve It)
