> Intervals.prefix() takes its input and builds a CompiledAutomaton, before passing this on to a new MultiTermAutomatonIntervalsSource.  However, while PrefixQuery.toAutomaton() builds a binary automaton, we don't tell CompiledAutomaton this and so it (incorrectly) does some unicode conversion on its input.
