While cache-ing followers' avatars, there have been a couple that I
couldn't snag with PHP curl. I get the "access denied" message. Those
avatar image file names have special characters in them such as é and

I've tried this:

$url = "http://a1.twimg.com/profile_images/57719746/'". JPEGstring_with_é ;
$url=urlencode($url );
$url= htmlentities($url);

so far, nothing I've tried works.
