// Need to explicitly set the state(mbstate_t) to zero.

// How to do this is not specified by the ISO C99 standard, so we

// might need to add some operators to make the intuiative case

// work:

//   w_codecvt::state_type state00;

//   state00 = 0;  

// or, can use this explicit "C" initialization:

//   w_codecvt::state_type state01 = {0, 0};

// .. except Ulrich says: Use memset. Always use memset. Feel the force...
