With quite recent versions of OGR you can force the client encoding
using the PGCLIENTENCODING environment variable.  This is touched on
in the online docs at:


The latest FWTools for linux or the gdal-dev package in OSGeo4W will
include these changes. I'm not sure whether the changes are in 1.5.x

The desired model for OGR is that each driver translates things to/from
UTF-8 unicode when reading and writing - which is the default action
of the postgres driver now.  However, some OGR drivers - like shape -
do not yet do this which results in non-unicode data getting to the
postgres driver.
