Use FilterDescriptor for international encodings (chars with accents)

Simple question... I have a service which returns the users and I implemented a FilterDescriptor which calls that service to populate a grid.

The filterdescriptor has the Contains oper开发者_如何学Cator and it works fine as far as the user's first or last name does not have accents. If I want to search for the 'Gómez' is my table, I want to be able to just type 'gomez', but that it's not working.

Is there a property or something I'm missing? How can I achieve that?
