  @file           geo47.h
  @author         JoergM
  @special area   UNICODE and other string conversions
  @brief          Defines data types and definitions for unicode handling
              This is currently reduced to what is needed for ggg90 and
              vgg90.cpp, but it is expandable...
              The whole stuff makes it compatible with "TCHAR.H"...
  @see
