I have another kind of problem related with MB and 6.5.3.

On FreeBSD 3.1:

nature=> select u_address from users;
u_address
------------------------------
Москва, Университетский пр. 13
(1 row)

nature=> set client_encoding to 'WIN';
SET VARIABLE
nature=> select u_address from users;
u_address
------------------------------
mOSKWA, uNIWERSITETSKIJ PR. 13
(1 row)

It seems that 8-bit was stripped !
I've checked locale on this machine - it works.

Moreover, 8-bit stripped even if I do silly setting of client_encoding
to native encoding:

ature=> set client_encoding to 'KOI8';
SET VARIABLE
nature=> select u_address from users;
u_address
------------------------------
mOSKWA, uNIWERSITETSKIJ PR. 13
(1 row)

It's interesting that on Linux I have no problem.
I have no time right now to test 6.5.2 but I recall I had no
such problem (not 100% sure).

    Regards,
        Oleg
