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