In my (Zend Framework 2) application I have a catalog of cities with links to sports pages:

page "Cities" (/catalog)
Madrid link: website.tld/catalog/Madrid
Berlin link: website.tld/catalog/Berlin
London link: website.tld/catalog/London

page "Sports in London" (/catalog/London)
Foo link: website.tld/catalog/London/Foo
Bar (Bar) link: website.tld/catalog/London/Bar (Bar)
Baz - Baz link: website.tld/catalog/London/Baz - Baz

The URLs are escaped and work well. But when I try to reach a page with an unescaped special character like a brace (e.g. "website.tld/catalog/Berlin/Jeu de Paume (Real Tennis)" instead of "website.tld/catalog/Berlin/Jeu%20de%20Paume%20%28Real%20Tennis%29"), I get a 404 Error.

How to fix it?

What I want to achieve is a behaviour like à la Wikipedia -- You can use "http://en.wikipedia.org/wiki/Signal_(electrical_engineering)" or "http://en.wikipedia.org/wiki/Signal_%28electrical_engineering%29" and will always get the corect page.
