Delete the line "utf8" in data

[turik97]

Ok people, since I had problems with this script since the beginning (First it was selenium issue for which I had to rewrite the driver location, then the config file was not getting parsed correctly, now the mentioned crash above which was solved by commenting the utf8 line as was advised) I want to post working as of 28/03/2024 version of visa.py which is running right now and was able to catch a slot within the specified range.
(please note that this script works without the config.ini and you need to include your data in the provided variables)

Hi, could you help me by explaining what exactly you mean by the utf8 line?
Thanks
