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

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.
