select / replace for the whole table

hello there
I had the problem to select and replace some strange symbols from a csv file into  umlaute such as ä, ö, ü
on various columns..
thanks to Michael Berthold there is now an elegant solution to it: :-)
the worklfow is as follows:

1. Column List Loop start

2. Extract Column header (use the Port 2 so the one at the bottom as output!!)

3. Java snippet (simple)
   copy into the Method Body the following:

$Column 0$=$Column 0$.replace ("ü","ü");
$Column 0$=$Column 0$.replace ("è", "è");

$Column 0$=$Column 0$.replace ("ä","ä" );

$Column 0$=$Column 0$.replace ("ö","ö");
$Column 0$=$Column 0$.replace ("ô","ô" );
$Column 0$=$Column 0$.replace ("é","é");
$Column 0$=$Column 0$.replace ("Ö","Ö");

$Column 0$=$Column 0$.replace ("É","E");
$Column 0$=$Column 0$.replace ("Ãœ","Ü");
return $Column 0$;

Set on  Replace Column   and on String!!!

4. Loop End (Column Append)
