Michael McCandless commented on LUCENE-2514:
--------------------------------------------

Ahh sorry I do indeed seek to an unpaired high surrogate -- easy to fix (pair it up w/ minimum low surrogate).

But, there's another problem, which is that the pre-flex codec uses Term.compareTo, and it needs that to be based on UTF16.  We can just fix the preflex codec to use its own (UTF8inUTF16order) comparator.  I *think* once we fix those two the test should pass again (crossing fingers...).

> in LUCENE-2426, the sort order was changed to codepoint order.
> unfortunately, Term is still using string internally, and more importantly its compareTo() uses the wrong order [utf-16].
> So MultiTermQuery, etc (especially its priority queues) are currently wrong.
> By changing Term to use bytes, we can also support terms encoded as bytes such as numerics, instead of using
> strange string encodings.
