Any thoughts on carrying this one step further. I've the case where I need
not just case insensitivity, but more of an interleaved case sensitivity.
For example using the following:

   int CompareInterleavedCaseChar( char a1, char a2 )
           if( std::toupper(a1) < std::toupper(a2) ) return -1;
      else if( std::toupper(a2) < std::toupper(a1) ) return 1;
      else if( a1 < a2 ) return -1;
      else if( a2 < a1 ) return 1;
      else return 0;

results in the following ordering:


in other words A < a < B < b < C ...
