    //   Persistence of C-style char* strings

    //   These are handled differently to other pointer types

    //   Warning! This means that pointers to char cannot be supported, since there
    //   is no type difference between a pointer to char and a C-style array of char.

    //   Warning! The restore deletes any old value of the data parameter and
    //   allocates a new char* which is (just) big enough and assigns it to the data
    //   field. This is because there is no way of knowing how long a char* is so
    //   the passed parameter is not safe to use. The allocation is done using
    //   standard new. If the data field is non-null on entry it will be deleted by
    //   standard delete. Best to make it null in the first place.
