Little problem with tsearch

Having a little problem with 7.3's tsearch:

usa=# select brand,description, ftiidx from food_foods where description
ilike '%frapp%';
brand | description
| ftiidx
-----------+----------------------------------------------------------------
-------+--------------------------------------------------------------------

Starbucks | Ice Blended Drinks: Creme Frappuccino® Coconut
| 'ice' 'blend' 'creme' 'drink' 'coconut' 'starbuck' 'frappuccino®'
Starbucks | Ice Blended Beverages: Frappuccino® Choc. Brownie
| 'ice' 'choc' 'blend' 'browni' 'beverag' 'starbuck' 'frappuccino®'
Starbucks | Ice Blended Beverages: Frappuccino® Coffee
| 'ice' 'blend' 'coffe' 'beverag' 'starbuck' 'frappuccino®'
Starbucks | Ice Blended Beverages: Frappuccino® Espresso
| 'ice' 'blend' 'beverag' 'espresso' 'starbuck' 'frappuccino®'

See how the (r) symbol is not being stemmed? That means that it's not
possible for anyone to search for the word 'frappacino'. Is there any fix
for this? A similar thing happens with the tradmark symbol.
