Also we need project name policy.
It's easy with "Wikipedia". "Encyclopedia" is an international word in the vast majority of modern languages, but we have project name in different alphabet. http://meta.wikimedia.org/wiki/Final_logo_variants/Nohat#Version_X
It's quite another matter with WikiSource. Word "Source" is not easy to translate. So, example, en Russian, we have "Викитека" (WikiThek) that literally means "WikiLibrary". In Hebrew it's "WikiText" See http://wikisource.org/wiki/Wikisource:Project_namespaces
