Result with special caracters and without them doesn't show the same result

I use refinerycms 3-0-0-stable , refinerycms-acts-as-indexed 2.0.0, and refinerycms-search on master.

I'm working on a fix with this branch : https://github.com/refinery/refinerycms-search/tree/fix-unicode and https://github.com/refinery/refinerycms-acts-as-indexed/tree/fix-unicode

This is the same error as #61
