title: MongoDB/PHP doesn't like Russian characters
body: <p>We're using MongoDB and PHP to handle IPNs from PayPal. The problem is we've had a number of customers from Russia and, try as I might, I can't get MongoDB to store the data correctly.</p>
  
  <p>For example, we had a customer called Юлия with a Russian address with similar formatted characters. If I print this out directly in PHP it displays correctly but if I put it into MongoDB and call it back I just get Ð®Ð»Ð¸Ñ</p>
  
  <p>I've tried various encodings but every time MongoDB seems to return the wrong text. How should I format the text to store these characters in MongoDB and be able to retrieve them? Do I need to convert them to one format for storage and then convert them back again for display?</p>
