can't access them. (which is to say I couldn't figure out how, though I didn't try ZServer standalone and I suppose apache might be doing something to the URI) You can't create objects with ids containing + or % or a host of other characters though (and btw the error message you get when you try is horrid, those characters are not illegal in URLs, illegal in the zope object model perhaps, but not URLs). I'm currious, why aren't arbitrary characters allowed in object ids? Well, because of the implementation details, it is not possible to allow certain ids (things that start with '_' or 'aq_', etc.).
Why % is not allowed I can only guess at, but I'd assume that the authors tried to get "sane" ids. It's a bit like the Unix Filesystem. By definition it allows all characters except '\0' and '/'. Still it's rather stupid and inconvienent to use exotic characters. By the way, you can look Zope/lib/python/OFS/ObjectManager.py:checkValidId (line 49) to see what is allowed and what not. Andreas
