When i use php (all version) with oci8 version 8.1.7 on linux, all character like ???? etc, are converted. 

script: 
<?

// connection a la base linux
$c = ocilogon("toto","totopass","linux");

$sql = "select * from toto_table where fonction like 'g%'";
$stmt = ociparse($c, $sql );

ociexecute($stmt);

$nb_row = ocifetchstatement($stmt, $result);

echo $nb_row;

for($i=0;$i<$nb_row; $i++)
 echo $result["ID"][$i]."--".$result["FONCTION"][$i]."<br>";
 

?>

Fonction value is "g?n?rique" and appear "generique" on web page.

The same script on windows platform with oci8 8.1.6 works fine. (on the same database all rights).

I need patch rapidly...

Thanks
