Re: UNICODE/UTF-8 on win32

UNICODE/UTF-8 does not work on the win32 server. The reason is that
strcoll() and friends don't work with it. To support it on win32, it
needs to be converted to UTF16 and use the wide-character versions of
the fucntion. Which we do not do.
(See
http://archives.postgresql.org/pgsql-hackers-win32/2004-11/msg00036.php
and
http://archives.postgresql.org/pgsql-hackers-win32/2004-12/msg00106.php)

I don't *think* we need to disable ito n the client. AFAIK, the client
interfaces don't use any of these functions, and I've seen reports of
people using that long before we had a native win32 server.
