It seems like I'm missing a call to FileUtils.RemoveInvalidCharacters.

It seems like I'm missing a call to FileUtils.RemoveInvalidCharacters.

Actually, I think this part is fine.

I think the problem is the commas and square brackets.

For extra safety, I think we should also exclude ascii control characters in the regex.
