PostgreSQL version: 8.1.4

Description: Unicode on Windows: aogonek is not distinguished from
agrave

It seems that on Windows PostgreSQL v8.1.4 does not distinguish aogonek
(U+0104, U+0105) from agrave (U+00C0, U+00E0):
CREATE DATABASE tests ENCODING = 'UTF8';
\c tests
CREATE TABLE foo
(
bar char(1) PRIMARY KEY
);
-- OK
INSERT INTO foo (bar) VALUES ('Ä
');
-- ERROR: duplicate key violates unique constraint
INSERT INTO foo (bar) VALUES ('Ã ');
-- Same thing with capitals
-- OK
INSERT INTO foo (bar) VALUES ('Ä');
-- ERROR: duplicate key violates unique constraint
INSERT INTO foo (bar) VALUES ('Ã');
