If by convert to char* you mean cast to char* then no, it will not
work. If you mean casting each element of what will be a short* to a
char* then yes it will work (assuming that all characters are ASCII)
but again you will be copying every character of that string
one-by-one, which is exactly what the marshaller does anyway.
