Zend_Cache And UTF-8 Problem

Question

I'm trying to save UTF-8 characters with Zend_Cache (like Ť, š etc) but Zend_Cache is messing them up and saves them as Å, ¾ and other weird characters.

Here is a snippet of my code that saves the data to the cache (the UTF-8 characters are messed up only online, when I try it on my PC on localhost it works ok):

// cache the external data
$data = array('nextRound' => $nextRound,
              'nextMatches' => $nextMatches,
              'leagueTable' => $leagueTable);
$cache = Zend_Registry::get('cache');
$cache->save($data, 'externalData');

Before I save the cached data, I purify it with HTMLPurifier and do some parsing with DOM, something like this:

    // fetch the HTML from external server
    $html = file_get_contents('http://www.example.com/test.html');

    // purify the HTML so we can load it with DOM
    include BASE_PATH . '/library/My/htmlpurifier-4.0.0-standalone/HTMLPurifier.standalone.php';
    $config = HTMLPurifier_Config::createDefault();
    $config->set('HTML.Doctype', 'XHTML 1.0 Strict');
    $purifier = new HTMLPurifier($config);
    $html = $purifier->purify($html);

    $dom = new DOMDocument();
    // hack to preserver UTF-8 characters
    $dom->loadHTML('<?xml encoding="UTF-8">' . $html);
    $dom->preserveWhiteSpace = false;

    // some parsing here

Here is how I initialize Zend_Cache in the bootstrap file:

protected function _initCache()
{
    $frontend= array('lifetime' => 7200,
                     'automatic_serialization' => true);
    $backend= array('cache_dir' => 'cache');
    $this->cache = Zend_Cache::factory('core',
                                       'File',
                                       $frontend,
                                       $backend);
}

Any ideas? It works on localhost (where I have support for the foreign language used in the HTML) but not on the server.

Are you absolutely sure its not the Purifier processing thats meesing it up? What happens if you eliminate that part of the process? — prodigitalson, Feb 10 '10 at 00:38
I'm 99% sure. I tried eliminating the HTMLPurifier part of the process and the problem persists. — Richard Knop, Feb 10 '10 at 00:45
Post your mbstring configuration in php.ini on localhost and server please — mike, Feb 12 '10 at 20:12
Hi Michal. I have actually found out it was DOM that was messing with UTF-8 characters, see this question: http://stackoverflow.com/questions/2236889/why-does-dom-change-encoding — Richard Knop, Feb 12 '10 at 21:25

I had a similar problem with a FPDF deployment. Here, the html space character &nbsp was being converted into that same Å character that you're getting here. It was fine on my local windows, but did not work in my linux server environment.

Try this:

$str = iconv('UTF-8', 'windows-1252', html_entity_decode($str));
