Legal page names
I have to think this is in RTFM territory, but is there a list somewhere of the legal characters for page names? I have looked and looked and can not find it anywhere.
I am setting up a wiki for chemistry and that means many of the names I would like to use as page titles have parentheses, brackets, +, -, and other symbols in them. While they seem to work in general, I am often finding features elsewhere that conflict (for instance the (alias()) feature just does not like parentheses in the title, something which is very bad for me - bug or am I using an illegal character? I just don't know).
I just want to know before I get to far along what characters work by specification and which ones just happen to work sometimes.
