Unicode problems on IRC

Hey guys,

The 'Unicode characters above 0x10000' issue keeps rearing its ugly head
in the IRC channel. I propose that it be fixed, even backported...

This is John Hansen's most recent patch to fix it:

http://archives.postgresql.org/pgsql-patches/2004-11/msg00259.php

And from what I can tell it was committed, then reverted because it
wasn't a "bug". It was going to go in for 8.1.

We on the channel are starting to think that it is in fact a bug. There
are are people with legitimately utf-8 encoded XML documents that they
cannot store in PostgreSQL. Apparently in the distant past, Unicode was
limited to 0x10000, but then was extended.

Perhaps we can reopen this case...

Chris
