This fix from https://forum.backbox.org/software-support/whatweb-problem/ worked for me, it's just updating the file to what's found here: https://github.com/jmhodges/rchardet/blob/master/lib/rchardet/universaldetector.rb
Apparently gem update should fix it but it didn't for me. I'm not a ruby person but setting the version of the rchardet gem to a more recent version should fix the issue for good.
sudo nano -c /usr/lib/ruby/vendor_ruby/rchardet/universaldetector.rb
Add on first line:
# encoding: US-ASCII
This is interesting.
Try executing
gem update rchardet
This patch to the rchardet gem was made in 2014.
