I guess arranging a string with a bunch of null terminations scattered through out it to delimit the parts would work, but to me that seems a less standard approach than simply using an array of pointers to strings. My feeling is the present approach will interface well with standard string handling methods for the various languages we support. That proved to be the case for python/numpy since that combination has an object (a numpy array of pointers to strings) which maps quite well to the present const char ** text. However, that is only one interfacing case so far, and I am willing to keep an open mind about changing the present approach if we run into trouble interfacing const char ** text to other languages.
