/* This file contains unicode support routines for the windres
   program.  Ideally, we would have generic unicode support which
   would work on all systems.  However, we don't.  Instead, on a
   Windows host, we are prepared to call some Windows routines.  This
   means that we will generate different output on Windows and Unix
   hosts, but that seems better than not really supporting unicode at
   all.  */
