encoding: square characters seen in openoffice base with postgresql 9.3

Hello,

I use linux system as desktop and another one for server which runs  postgresql 9.3
When connecting with openoffice 4.1.1 Base, select syntax returns text separated by a strange square character.
It seems to be a coding fault. My data are encoded with utf8 and all works fine with pgadminIII
I have already set the properties of OpenOffice Base to support UTF8.
The version of my driver is 09.03.0400 p, li { white-space: pre-wrap; }

Please tell me how to get the right text without squarre characters

Bellow are the configuration of odbc.ini
