Okay, I changed 2 things. use utf8; at the start. And i fixed the error in line 36:

print "$testname failed on psql readback. Got $resulttest2 where $test
+ was expected.\n";

Now I get this, which I must admit, looks better:

...
test2 is successful on DBI readback.
psql raw results: <table border="1">
  <tr>
    <th align="center">test</th>
  </tr>
  <tr valign="top">
    <td align="left">äöüßÄÖÜ</td>
  </tr>
</table>
<p>(1 Zeile)<br />
</p>

test2 failed on psql readback. Got äöüßÄÖÜ where &#65533;&#65533;&#655
+33;&#65533;&#65533;&#65533;&#65533; was expected.

I don't understand why I get the question marks in the variable test, but my problem seems to be fixed. Many thanks. I was missing the obvious it seems. ;o)
