For future proofing, it would be good to encode each category on its own, in such a way that related categories are grouped together numerically. Perhaps the lowercase and uppercase letters, which need case-changing tables, should still be last in the encoding.
There's really nothing to future-proof: the number of general categories is fixed, although it's possible that some characters may change categories.
