MrsColumbo,
Sorry for the delayed response. We monitor the forums on the weekends, but aren't always able to get to every post.
As to your question.. both Facebook and LinkedIn use what are called "Open Graph" tags to describe the page. These let you (the administrator) set the title, description, and image for the page whenever it's shared on Facebook or LinkedIn. When the Open Graph tags aren't set, then both services will analyze the page and pick out the content the think best represents the page.
JLinked currently doesn't offer Open Graph support, but we're expecting to include it in the next release (1-2 months).
However, until then, we should be able to help you fix the weird characters, but we need some more information. Facebook has a tool where you can see how Facebook 'sees' your page:
developers.facebook.com/tools/debug/og/o...agazin-online.com%2F
You'll see in the description area, that the special characters are incorrect. At the bottom of the page is a link to "See exactly what our scraper sees for your URL". If you click into there, you'll see the special characters were returned (or at least interpreted by) Facebook.
Some suggestions on how to fix:
1) Try with a different template. When I use the Atomic template (that comes with Joomla), the description is correct in the debug tool:
developers.facebook.com/tools/debug/og/o...%3Ftemplate%3Datomic
I don't know what about the templates is different, but it seems as though something is being set incorrectly in your template.
Other suggestions that may work with the current template, but I think #1 above is the main culprit:
2) Try disabling GZip compression. Compressing the text can cause some translation issues that browsers handle, but Facebook's automated tools can have issues with.
3) The Response Code that Facebook is showing from your page is 206. This is not the normal response code (200) and could be the problem. That's a server configuration issue, and I'm not sure what's causing that. Usually, it's a sign of an aggressive caching setup which tries to return the page in pieces, and could cause the whole document to not be interpreted properly.
Just so you know, each time you run your page through the debug tool, the page should be refreshed. That way, you can see your change immediately to see if they had a positive effect.
Hope that helps get you started,
Alex
