Consider implementing a special field that of the form accentfolded|original
For instance, you'd index something like ecole|école ecole|école privée as _terms_, not broken up at all. Now, when you send something to the suggester you send just "eco" or "éco" you fold them to "eco" too and get back these tokens. Then the app layer breaks them up and displays them pleasingly.
