What about PRIMARY KEY? If i use ascii symbols, all works fine:

postgres=# insert into test values( 'asdf asdf' );
INSERT 0 1
postgres=# insert into test values( 'asdf asdf' );
ERROR:  повторный ключ нарушает констрейнт
UNIQUE "test_pkey"

TIP 9: In versions below 8.0, the planner will ignore your desire to
       choose an index scan if your joining column's datatypes do not
       match
