#60 content-center search invalid URLs

[Steve Pugh]

We were getting a problem in content-center searches:
1. Do a search
2. Hit "next>>" several times,
3. Aplaws produces invalid (tto long) URL, with too
many %C2%A3 type characters.

Cause: UTF-8 encoding type issue (issue is likely to
depend on what encoding is neing used)

Solution: Avoid problem by not using special chararcter
( ) in form parameter.
