Steps will reproduce the problem

1. Add a cart item with a (c) copyright character in its name and/or description.
2. Send the cart to Checkout.
3. Checkout doesn't display they (c) character.

Expected output

The (c) character (or any other "high ASCII" character) should be displayed properly. The reason it's not displayed is probably because these special characters aren't UTF-8 encoded. See here for how Checkout wants requests encoded: http://code.google.com/apis/checkout/developer/index.html#api_request_guidelines

Fixed in version 0.7.1 and above.
