ASP.NET 5 why html doesn't display cyrillic?

Question

ASP.NET

How to make sure that when forming the html page, the words were in Cyrillic, and not in the encoding?
Controller example.

public IActionResult Index()
{
return View(db.Products.ToList());
}

Index.cshtml example

@model List<Product>
@foreach (var product in Model)
{
<a asp-controller="Product" asp-action="Show" asp-route-name="@product.CaseName">
}

As a result, when viewing the markup in the browser, the link will be of this type.
<a href="/%B2%D0%B0%D1%BE">&#x421;&#x440;</a>
How can you get such a result?
<a href="Тостер">Тостер</a>

It doesn't work, this problem is hidden in the entity framework, because if I just add something in Russian in the file, it will be displayed correctly.
