client_encoding / postgresql strange behaviour

>Hi, as far as I've understood client_encoding tells postgresql

>Postgresql will do the conversion for you if the database encoding is different.

>I've a unicode database and the line

>(this is the same as calling set client_encoding='latin1' on any connection right?).

>Now i want to read the data using :
>1) if i read the first row keeping client_encoding latin1 everything is OK (i get hex 92 back)
>2) if i read the 2nd row setting client_encoding unicode everything is OK (i get the 3 unicode bytes)
>3) if i read the first row setting client_encoding unicode IT DOES NOT WORK I get a 2 byte sequence c2 92 ?? so i see garbage.

>WHY this does not work (can't i write in one encoding and read in another?)
>Looks like postgresql did not correctly converted from latin1 to unicode and has gargabage inside
>(but why do i read correctly the first line when i have client_encoding latin1) ?
