I think the only meaningful categories are those defined by Unicode. That is, a block of Cyrillic characters should have the cyrillic category, the block of Japanese characters should have japanese category, etc. The fact that the character is covered by some ISO-2022 charset is not interesting in Emacs 23, unless I'm missing something. What kind of backward compatibility problems could we cause? Who or what code depends on these categories?
