Re: 'order by' does "wrong" with unicode-chars (german umlauts)

It makes no difference if I use a database with encoding unicode:


# \l
               List of databases
        Name        |    Owner     | Encoding
--------------------+--------------+-----------

 test               | peter        | SQL_ASCII
 unicode            | peter        | UNICODE
 unicode2           | peter        | LATIN1


I tried with all these databases. The problem stays exactely the same. The
german umlaut-O appears as double-byte "ö" and when ordering it appears between
"A" and "B", cause imho only the first byte "Ã" is taking into account.

I still have no idea, if there is a problem outside postgreSQL (in perl or maybe
in the DBD::Pg-interface) or inside postgreSQL. I still struggle with serious
debugging cause I dont know how to insert "real" unicode into postgres ... Any
debugging-hints welcome also :)


Dealing with the UNICODE-database raises new problems: 
unicode=# insert into test values ('österreich');
ERROR:  Unicode >= 0x10000 is not supported
unicode=# show client_encoding;
 client_encoding
-----------------
 UNICODE
(1 row)


thnx,
