Entity Framework C# Insert Data russian encoding problems

I'm using an EDM model in my project.

When I insert russian words in the database via a post request I get ??????

Controller:

[Authorize]
[HttpPost]
public string DescEdit(FormCollection formValues)
{
    var CurrentUserPhoto = User.Identity.Name;
    string x = Request.Form["id"];
    Int64 id = Convert.ToInt64(x);
    photos upPhotoDesc = photosRepository.GetPhotosById(id, CurrentUserPhoto);
    upPhotoDesc.description = Request.Form["value"];
    photosRepository.Save();

    return Request.Form["value"];
}

1. In the database all charset are set to utf-8
2. In the layout page content enc type is utf-8

Database code:

CREATE TABLE `photos` (
  `id` bigint(255) NOT NULL AUTO_INCREMENT,
  `done` tinyint(1) NOT NULL DEFAULT '0',
  `imgsmall` varchar(255) NOT NULL DEFAULT '',
  `imgcrop` varchar(255) NOT NULL DEFAULT '',
  `imgmiddle` varchar(255) NOT NULL DEFAULT '',
  `imgbig` varchar(255) NOT NULL DEFAULT '',
  `full_size` varchar(255) NOT NULL DEFAULT '',
  `description` varchar(255) DEFAULT NULL,
  `name` varchar(255) DEFAULT NULL,
  `permission` tinyint(1) NOT NULL DEFAULT '0',
  `userid` int(11) NOT NULL DEFAULT '0',
  `userlogin` varchar(255) NOT NULL DEFAULT '',
  `rating` smallint(5) DEFAULT '0',
  PRIMARY KEY (`id`),
  KEY `indx_photos_1` (`id`,`userlogin`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE utf8_unicode_ci;
