Hi!

I dug through my list-archives - I actually used to have the very same problem 
that you described: special chars being swallowed by tsearch2-functions. The 
source of the problem was that I had INITDB'ed my cluster with [EMAIL 
PROTECTED] as locale, whereas my databases used Unicode encoding. This does not 
work correctly. I had to dump, initdb to the correct UTF-8-locale (de_DE.UTF-8 
in my case) and reload to get tsearch2 to work correctly. You may find the 
original discussion here: 
http://archives.postgresql.org/pgsql-general/2004-07/msg00620.php
If you wish to find out which locale was used during INITDB for your cluster, 
you may use the pg_controldata program that's supplied with PostgreSQL.

Kind regards

   Markus
