You give little detail, but it seems that your software is encoding HTML
entities twice. But that looks like a too serious bug to remain
unnoticed until now.

As I said, you need to actively encode HTML entities twice in order to
get this:

$url = 'http://mysite.com/index.php?language=fr&osCid=xxxxx';
$url = htmlspecialchars($url);
echo '<a href="' . htmlspecialchars($url) . '">Home</a>';

Check the code.

I would not play with that, it can only lead to even more obscure bugs.
