Why would you expect a page name starting with a non-letter to work? i'm not aware of ANY wiki which allows wiki works to start with non-alpha characters (and most require CamelCaseWords). Fossil doesn't have a 100% generic document management system - it has a wiki, and wiki conventions call for certain naming patterns. Granted, fossil's naming conventions are "more flexible" than most wikis, but i would never expect a page name starting with a dot to work.
