What you're seeing is artifacts of the "Preserve Address Book data"
setting. Well-behaved applications shouldn't show these characters
(they're invisible Unicode characters) but many do. You can get rid of
them by switching to Gmail compatibility mode:
* In the Contacts tab, disable then re-enable the "Sync contacts"
option
* Select "Preserve Gmail compatibility"
* Click "OK"
* Force a push by making some small change to one of your Address Book
contacts
* Sync
When you switch modes, some contacts in Address Book might show
unusual changes (like doubled first names) after the first sync. If
so, just manually clean them up in Address Book and sync again. The
problem shouldn't recur.
Please let me know if you have any questions or run into any
problems.
Thanks,
Charlie
