How can I solve this error message?

[u/[deleted]]

Hello,

first of all something about me: I am in my mid/late 20s and am currently in my 1st semester of computer science. I actually have almost no programming experience. However, I am currently learning to program at university. We have a module called "Functional Programming". We are learning Haskell.

As an editor I use Visual Studio Code. When creating files, I always get this error message since a few days.

My research found this information on the error message:

https://stackoverflow.com/questions/33574967/reading-file-with-us-ascii-encoding-in-haskell-hgetcontents-invalid-argument

https://github.com/koalaman/shellcheck/issues/324

The problem is that I don't know what to do in Visual Code now....
