UTF fix #36

Proposed edits to the tropo.class.php file to fix UTF:

• Open it and search for this piece of text (it should be around line 667) - return str_replace(array("", ""{", "}""), array("", "{", "}"), $json);
• Once you find it, replace it with this - return str_replace(array('"', ""{", "}"", '\/', '\'), array('"', "{", "}", '/', ''), $json);
