1337 is not exactly supported. It's not something you could select in your preferences to be the wiki's interface. However, the content of a wiki can be in any language, real or not. There are wikis about and in constructed languages, such as Babyish and the Conlangs wiki. Some constructed languages are supported, including Esperanto, Ido, Toki Pona, and Klingon. Of these, Esperanto is the most popular with 13 wikis including Esperanto editions of Uncyclopedia and Memory Alpha.
