Well, I would argue with that.
I was in the situation where psql shows chars correctly, but them has been
showed incorrectly by java.
And the reason is that:
(quete from Barry Lind's email)
Now it turns out that Postgres is a little lax in its character set
support, so you can very easily insert char/varchar/text with values
that fall outside the range of valid values for a given character set
(and psql doesn't really care either). However in java since we must do
character set conversion to unicode, it does make a difference and any
values that were inserted that are incorrect with regards to the
database character set will be reported as ?'s in java.

I have been hit my toe to stone once with that problem, and the cure
was: There have to be backend compiled with multibyte support, and set up
with correct char set.
IMHO, the main problem is that 8-bit speaking people don't think that they
will need multibyte support. If you figure that out, you will be salvaged
because the actual multibyte doc is very good and clear.
