Special chars in project directory

[juniorklein]

I had a big problem when trying to use BartyCrouch. This was not my first project which made me even more confused. After hours of debugging, I identified that the problem was in the project directory, that there were special characters in its name (accents).
BartyCrouch couldn't find any of my files (localizable, interfaces, storyboards ...)

A good idea would be to document that this type of problem can occur. What do you think?

@juniorklein Thank you for reporting the problem. Yes, of course we could document it. Feel free to open a PR with an improvement in the README.md. Other than that, it would also be great if you could mention an example name here which didn't work so we can fix it and even write tests with exactly that example so it doesn't happen in the future again once fixed.
