[xwiki-devs] Valid XWiki Page Names

Hello Devs, is there some Documentation (or a Regex) which Characters are practically allowed in page and space names? I am unable to find this. From the syntax page it is kind of clear that the following ones are not really usable: "." Because of Space Prefix "[]" Link itself "()%" new formatting characters ">" alias of links I was playing around and if you enter some page name like "hello.hello.hello" you'll get a page named "hello" in the Space "hello.hello". If you enter "hello\.hello" it'll just display nothing. (on XWiki 1.7 M2) Maybe XWiki should check if the given page or space name is actually valid, before creating the page? Nice greetings Jonas
