initdb / Unicode

Hi

I've just done an installation on Windows 2000 and was going to ask why
Unicode wasn't offered by the installer's initdb, but that question's
answered here:
  http://archives.postgresql.org/pgsql-hackers-win32/2004-12/msg00032.php

How about putting that in the FAQ? Also, how exactly is Unicode encoding
broken on Win32? Is it a problem if I create a database post-install with
Unicode encoding?

Thanks
