Yonik Seeley commented on LUCENE-2426:
--------------------------------------

big +1
the more we get to pure bytes, the better IMO.

> Since flexible indexing, terms are now represented as byte[], but for backwards compatibility
reasons, they are not sorted as byte[], but instead as if they were char[].
> I think its time to look at sorting terms as byte[]... this would yield the following
improvements:
> * terms are more opaque by default, they are byte[] and sort as byte[]. I think this
would make lucene friendlier to customizations.
> * numerics and collation are then free to use their own encoding (full byte) rather than
avoiding the use of certain bits to remain compatible with char[] sort order.
> * automaton gets simpler because as in LUCENE-2265, it uses byte[] too, and has special
hacks because terms are sorted as char[]
