Dimitris,
Very sorry for the delay in getting back to this. We've done a lot of research, and have a minor code change we'd like you to try and implement to see if it fixes the problem you're having. Basically, we do a lot of manipulation to the text of the article to try and make sure only real text is used for the description, and it looks like one of our changes are changing 'good' characters to bad ones.

To fix, please edit the /libraries/sourcecoast/utilities.php file. Around line 391, you'll see the following block of code:
// turn some HTML with non-breaking spaces into a "normal" string
        $converted = strtr($htmlText, array_flip(get_html_translation_table(HTML_ENTITIES, ENT_QUOTES)));
        $converted = trim($converted," \t\n\r\0\x0B".chr(0xC2).chr(0xA0)); // UTF encodes it as chr(0xC2).chr(0xA0)
Please edit that by removing those first 2 lines and replacing it as below:
[code]        // turn some HTML with non-breaking spaces into a "normal" string
        $converted = htmlspecialchars(strip_tags($htmlText), ENT_QUOTES, 'UTF-8');
        return $converted;
Please let us know how that goes, but hopefully it will fix you right up. Just so you know, I deleted the other duplicate post you made about this. It's easier to just continue this discussion.

Thanks, and good luck,
Alex

Hello Alex,
thank you for your reply, despite the fact that was a little bit late.
The new articles being published have no such problem.But, the old ones continue to be shared unnormally.Like this one www.agioritikovima.gr/pontiakos/10432-panagia-oumela
I think that maybe such articles need some days to be corrected.Don't you think?

When you make that change, new articles will automatically be detected properly. Other pages will need to have their cache refreshed by Facebook. You can use the Facebook Debug Tool to scan your problem URLs and verify that it will see the data correctly. Scanning a page manually should also update Facebook's cached data for your page immediately so you don't have to wait.

Hope that helps explain,
Alex

Dear Alex,
thank you for your interest.
You are right about the debugger.
I have noticed that in many articles, if a article picture is smaller in height than 170 px, then it does not appear in facebook share (www.agioritikovima.gr/mitropoleis/17020-o-ieraputnis-ka). The strange thing is that if i post only the www.agioritikovima.gr/mitropoleis/17020 url,then the picture appears normally.Could you explain that?
Should pictures have a minimum height or width?

I just ran the 2nd URL you posted into the Debug Tool. The following warnings were reported:

Small og:image: All the images referenced by og:image should be at least 200px in both dimensions. Please check all the images with tag og:image in the given url and ensure that it meets the recommended specification.
og:image not big enough: Provided og:image is not big enough. Image 'www.agioritikovima.gr/images/av1/eksomologoscompr.jpg' will be used instead.

So, I'd recommend start using larger images and then resizing them when inserting into an article. Otherwise, have a larger image available and use the {SCOpenGraph image=http://site.com/link-to-larger-image.jpg} so that a bigger image is used.

Hope that helps, but if you still need info, just let us know.

Thanks,
Alex

Glad to hear we could help. Should you need anything else, just let us know.

Finally, if you haven't already, please consider leaving a rating and review for JFBConnect, or our support, on the Joomla Extension Directory. It certainly isn't required, but is very appreciated:
