p:selectOneMenu filter not working with accented characters

I use PrimeFaces SelectOneMenu advanced. Filter is wrong working when I input the i and ı character.
For example http://www.primefaces.org/showcase/ui/input/oneMenu.xhtml demo advanced one menu I search arI and arİ strings and it finds Aristo element.

In my application, my menu contains Isparta element. I input Isp and İsp and filter finds Isparta.

How can I solve this problem?

Solution

I resolve this problem with autocomplete component. Primefaces autocomplete component with dropdown="true" property works like one menu and this component don't have Turkish character problem.
