Because I don't really know what this category is about?

I think that my confusion is a sufficient proof that more precise
documentation is needed.

A user might not know what exactly a "Unicode block" is.  (I don't.)
I think a pointer to some sources or a few words of explanation are
really needed.  (I won't make a patch, though, since I clearly know too
little about it to do it correctly.)
