Some Font Characters Doesn't Seem Properly On Android?

Question

For Android and IOS platforms same font used. It's looking good on IOS, but android doesn't show some characters like "Ş", "Ğ" properly.The below screenshot from android.

Seems it's not font specific problem beacuse on IOS working well.

<TextView
    android:id="@+id/txt_title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerInParent="true"
    android:fontFamily="@font/avenirltstd_book"
    android:text="Şikayet Grafiği"
    android:textColor="@color/white"
    android:textSize="@dimen/dp18" />

Is there any special way to show these characters with same font? Or the solution is to stop dealing with this and use different font ?
