When using the (R) trademark symbol in Groups the Group fails, and it cannot be deleted.

When adding a GROUP that contains a trademark ® symbol, the group fails and then cannot be deleted. I am attaching screenshots for additional details.

When you try to delete the group, the trademark is now = DOMEA®, however the group pages shoes DOMEA®.

Whey you try to view or edit the members no member show, however they are shown on the Browse Group page.

Try to Click the Group to view it, and error occurs that the Group does not exist.

We have tried to fix this in our DB, but we were unsuccessful.
