For your data, using a null byte instead of a space would be importeant. Actually that's why I chose /.\0*/gs instead of /[^\0]\0*/s. This means that the first character can be a 0, and every iteration after that it will never start with null because of the way regex work. Or technically, the idea crossed my mind, I realized it would still work by chance, and then forgot to mention it :)
