Robert Muir commented on LUCENE-2504:
-------------------------------------
bq. Yep, should be fine. Is there an upper bound on how long collated terms can
be?
There isn't, but...
I can't promise (but i'll verify), i think actually a single 0xff might do, for
the major encodings.
* its invalid in utf-8
* its technically valid, but unused (reset byte) in bocu-1
* collation keys i understand are a modified bocu, likely unused there too.
so its like a NaN sentinel, if someone is doing something very wierd, maybe it
wont work,
but in general, i think it will work. ill check.
