It seems that Iconv is broken in my case. I commented out the  
following code and my problems are solved:
File: Horde/String.php
Line: 147
->
         /* Try iconv with transliteration. */
         if (Horde_Util::extensionExists('iconv')) {
             unset($php_errormsg);
             ini_set('track_errors', 1);
             $out = @iconv($from, $to . '//TRANSLIT', $input);
             $errmsg = isset($php_errormsg);
             ini_restore('track_errors');
             if (!$errmsg && $out !== false) {
			echo "2";
                 return $out;
             }
         }
<-

I already tried to remove "//TRANSLIT" and tried to use "//IGNORE" but  
anythings fails.
