Wikipedia:Naming conventions (technical restrictions)
Some page names are not possible because of limitations imposed by the MediaWiki software. In some cases (such as names which should begin with a lowercase letter, like eBay), a template can be added to the article to cause the title header to be displayed as desired. In other cases (such as names containing restricted characters) it is necessary to adopt and display a different title. This page describes appropriate ways to handle these situations.
