French character issue using asp.net web api

Hi all i have the following problem when i make a request to an asp.net web api controller.

i submit the following text: VIDÉO, but when it gets to my controller action the text become: VID�O.

the problem is not when the data is posted to the server because i can see that the json data that is being posted to the server is correct. i tried all variation of the utf-8 character set but still have the same problem.

Thank you very much guys. looking forward to reading your comments.
