Cases are generic prefixes such as "x-". To some extent, Chinese might
be a real example, because (sorry if the tags are wrong) zh-cn (Chinese
in China) is written with simplified ideographs, and zh-tw (Chinese in
Taiwan) is written with traditional ideographs. I therefore already
have excluded this case in one of my proposals. Anyway, this still
leaves the case
