Episode 5: Specify the encoding when reading in JSON file

[milanmlft]

In episode 5, we're reading in the eva-data.json file. However, some participants got a UnicodeDecodeError because of the unicode characters present in the data.

Specifying encoding="utf8" when opening the file might help, although it might be worth figuring out why only some people got this error.

We need to find a way to recreate the error. It was no a Windows machine I think but not all Windows users got this error?

Indeed not everyone experienced this - but perhaps this machine was not using UTF-8 as the default encoding. Think we could either make this an improvent and a teaching point or just fix this in the started code.
