For the @steempytutorials I recommend going with with settings that are recommended. I installed a new droplet from digital ocean this week for the website. As long as you follow the #0 tutorial everything will work fine.
About the unicode, you might need to set your locales.
export LC_ALL="en_US.UTF-8"
export LC_CTYPE="en_US.UTF-8"
Also it is good practise to run your code on a server.
I have not the red new about Hivemind yet.
I followed the tutorial and even used a digital ocean droplet myself, the only difference is that I use Debian instead of Ubuntu but since Ubuntu is based on Debian it shouldn't make any difference.. I will try it again and set the Unicode locales, I had the language settings set to fit my German keyboard so that might have messed it up, thanks for the tip!
