This fixes a crash that happened when creating an instance of `std::string` from a `Swift.String` that contains non-ASCII characters. When converted to a UTF-8 array, such characters might be represented by numbers that fall out of `CChar`'s boundaries if they have a sign bit set to 1. This is normal and shouldn't trigger a crash or an assertion failure.
