Unwanted "recoding"

<p>We save some data in VISCII (Vietnamese TCVN). <p>Selecting the data with psql will return correct values, but when
Itry to access the data with libpgtcl.so, depending on the Server-encoding, some of the characters are changed.<p>I
triedto build the database without multibyte, but this feature seams no more to be available.<p>I tried also to set
client_encodingto TCVN, so the missed characters are O.K., but some others are exchanged.<p>How I can stop the
interfacethinking about my data, I just want back, what I putted in ;-))<p>Thanks, Steffen
