Google Base Product Feed XML errors

I'm getting errors with me feed.

it seems the database has not converted things like ° to ° and ± to ±

so its not putting any of my items in google shopping...

I have like over 1100 products....

is there a way i can format every product description to allow my feed to work?

Haven't tested or done any reading on Google product feeds so this is a guess:

You could try modifying catalog/controller/feed/google_base.php to change how the output is formatted. If you look at the line for the brand, it's calling html_entity_decode on the manufacturer (replacing any unicode characters with their html equivalents). If you copy that call to the other elements that you need to change (e.g. title) then that might fix it - or it might make the problem worse, idk.
