Re: 0xc3 error Text Search Windows French

Sorry one last detail.

All of my databases are in utf-8 format. My Windows XP is en_AU and
defaults to ISO-8859-1 character sets. My postgresql.conf is set to the
default for the client_encoding setting, which should then default to
the database utf-8 format.
