QueryParser fails badly allocating enormous amount of memory when
processing query strings with special/accented characters. See:
irb(main):002:0> require 'rubygems'
irb(main):003:0> require 'ferret'
irb(main):004:0> include Ferret
irb(main):005:0> index = Index::Index.new
irb(main):008:0> index << "something"
# Now the error while processing "bolô"
irb(main):009:0> query = index.process_query("bo\303\264")
