If such a symbol cannot be used in homepage:Special:CreateNewWiki, you might consider contacting Staff using Special:Contact, to have the wiki made manually, and specify the URL, SITENAME, and category of the wiki. Maybe they can give the wiki the desired different SITENAME. I really doubt that the URL could contain such a character, though, in any case.
