- Use "R" to cancel escape of string.
- Use ```gsl::narrow``` to cast from one type to another type when there may be a loss in the cast. If the cast does have a loss, for example, cast -5 to ```unsigned```, an exception will be thrown. If you want to cast it any way, you can use ```gsl::narrow_cast``` to explicitly show the cast.
