Encoding problem in attribute: description - Some of the characters in your items seem to be invalid. Please verify all the characters in your feed are valid for your selected encoding.

Microsoft uses a proprietary encoding (called CP-1252) for the bullet symbol and some other special characters, whereas most websites and data feeds use UTF-8. When you copy-paste from a Microsoft product into a website, some characters may appear as junk. Our system generates data feeds in the UTF-8 character encoding, which many shopping engines now require.
