TYPO3 Core

Hello,
I have configured Typo3 to use a Postgres DB (UTF-8).

I added
default_charset = "uft-8"
to the php.ini in the /etc/php5/apache2 directory.
I have Typo3 4.0 installed.

When I try to store content in the DB I get the error messages:

Warning: pg_query() [function.pg-query]: Query failed: FEHLER: ungültige Byte-Sequenz für Kodierung »UTF8«: 0xdcdc in /var/www/dummy-4.0.1/typo3conf/ext/adodb/adodb/drivers/adodb-postgres7.inc.php on line 115

Warning: Cannot modify header information - headers already sent by (output started at /var/www/dummy-4.0.1/typo3conf/ext/adodb/adodb/drivers/adodb-postgres7.inc.php:115) in /var/www/typo3_src-4.0.1/typo3/tce_db.php on line 225

When I add the following lines into the localconf.php I can store the data in the DB without an error.
But when I want to create a website out of this content, the website is empty. (the header exists but theres no content)

Is this a bug?
