"space" isn't an illegal character.

What will happen to those cases where M$ is involved and you download a site
for offline view and then decide to upload it into Zope.
You might save the webpage like "peter bengtsson.html" and with it comes a
folder full of images and stylesheets and they are all called using a space.
