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. */
