if len is zero, it will allocate enough memory to store the string pointed by Str and then copies the Str into it.
if len > 0, then it will allocate enough memory to store '''len''' chars, copying only len characters of str.
In any way, the allocated memory is pointed by '''_data'''. Also it will set the width to length of memory allocated.
