Ok the Unicode data here are too small for eytzinger to work. In fact, it is slightly slower than before (a few microseconds).

One interesting observation is that if I do the sorting statically, the compression ratio suffers significantly compared to the ascending layout. brotli looks very good for similar sequences that appear in order.

If I move the eytzinger sorting to the runtime, I can fix it, but it adds a small initialization cost. Since it doesn't improve any performance, I don't think it's worth introducing.
