Query comparison to character variable doesn't work

[nirinchev]

The following unit test fails:

public class Foo : RealmObject
{
    public char Bar { get; set; }
}

[Test]
public void TestCharacterComparison()
{
    char s = 'a';
    var result = _realm.All<Foo>().Where(f => f.Bar == s).ToArray();
}
