Honor�� and I had a debugging session during my sabbatical that was 2+ hours because of a frustrating hidden character that got inserted in a string that was executed in a Shell command. It was not possible to see it in the Pharo editor.��

It was a CTRL-X at some point, here's the commit where I removed it:��https://github.com/fuhrmanator/GitMiner/commit/0b1e564ba2c25fb9cf7dfa925b06367f66a02b9b

Hi

I have the impression that we can introduce hidden characters��
while typing code and this is a problem to me because we do not see them :)
I got for example selhiddenf and it can lead to strange situations.��

I will try to chase the key combinations that produce them and see how we
can control and avoid this situation.��
If you find the key combination please let me know.��
