I elected in the default case just to revert to existing behaviour for C 
strings. Terminate them on the first null regardless of the physical 
bounds of the array. And to provide the length option to override null 
detection.

It is tough choice, and I wonder if we'll run into similar issues with 
strings with other languages down the line.
