The garbage is super annoying. Please stop. Human scripts are O(N), too bad. You can build indices (must, for large documents), but you can't really avoid this being O(N). And we're not even talking about normalization. People get upset about these things and blame Unicode, but the problems are not with Unicode -- they are semantics problems with our scripts that Unicode deals with about as well as can be hoped for. The only thing I'd remove from Unicode is pre-compositions and the associated normal forms NFC and NFKC. But note that that wouldn't remove the need for normalization.
