Just installed the updated v2.0 version of Simple Contact Form. Problem is that Greek don't encode properly when sent through the page.
I tried to change character set in the .../views/public/index/index.php file of the plugin with no luck.
Greek load OK in any other case though, in Browse Items page, for example.
Can you post a short example of the kind of Greek source text that gets mangled?
If you're game for trying some small changes, I think the fix should be relatively easy here:
In the plugins's controllers/IndexController.php, change both instances of the following line (on lines 80 and 91):
$mail = new Zend_Mail();
$mail = new Zend_Mail('UTF-8');
Fixed. Thanks a lot John.
